+/**
+ * Distribution sampler that uses the Alias method. It can be used to sample from n values each with an associated
+ * probability. This implementation is based on the detailed explanation of the alias method by Keith Schartz and
+ * implements Vose's algorithm.
+ *
+ * Vose, M.D., A linear algorithm for generating random numbers with a given distribution, IEEE Transactions on
+ * Software Engineering, 17, 972-975, 1991. he algorithm will sample values in O(1) time after a pre-processing step
+ * of O(n) time.
+ *
+ * The alias tables are constructed using fraction probabilities with an assumed denominator of 253. In the generic
+ * case sampling uses UniformRandomProvider.nextInt(int) and the upper 53-bits from UniformRandomProvider.nextLong().
+ *
+ * Zero padding the input probabilities can be used to make more sampling more efficient. Any zero entry will always be
+ * aliased removing the requirement to compute a long. Increased sampling speed comes at the cost of increased storage
+ * space. The algorithm requires approximately 12 bytes of storage per input probability, that is n * 12 for size n.
+ * Zero-padding only requires 4 bytes of storage per padded value as the probability is known to be zero.
+ *
+ * An optimisation is performed for small table sizes that are a power of 2. In this case the sampling uses 1 or 2
+ * calls from UniformRandomProvider.nextInt() to generate up to 64-bits for creation of an 11-bit index and 53-bits
+ * for the long. This optimisation requires a generator with a high cycle length for the lower order bits.
+ *
+ * Larger table sizes that are a power of 2 will benefit from fast algorithms for UniformRandomProvider.nextInt(int)
+ * that exploit the power of 2.
+ *

-# AST based expression representation and operations
+# AST-based expression representation and operations (`kmath-ast`)
 
-## Dynamic expression code generation
-Contributed by [Iaroslav Postovalov](https://github.com/CommanderTvis).
\ No newline at end of file
+This subproject implements the following features:
+
+- Expression Language and its parser.
+- MST as expression language's syntax intermediate representation.
+- Type-safe builder of MST.
+- Evaluating expressions by traversing MST.
+
+## Dynamic expression code generation with OW2 ASM
+
+`kmath-ast` JVM module supports runtime code generation to eliminate overhead of tree traversal. Code generator builds 
+a special implementation of `Expression<T>` with implemented `invoke` function. 
+
+For example, the following builder: 
+
+```kotlin
+    RealField.mstInField { symbol("x") + 2 }.compile()
+``` 
+
+… leads to generation of bytecode, which can be decompiled to the following Java class: 
+
+```java
+package scientifik.kmath.asm.generated;
+
+import java.util.Map;
+import scientifik.kmath.asm.internal.AsmCompiledExpression;
+import scientifik.kmath.operations.Algebra;
+import scientifik.kmath.operations.RealField;
+
+// The class's name is build with MST's hash-code and collision fixing number. 
+public final class AsmCompiledExpression_45045_0 extends AsmCompiledExpression<Double> {
+    // Plain constructor
+    public AsmCompiledExpression_45045_0(Algebra algebra, Object[] constants) {
+        super(algebra, constants);
+    }
+
+    // The actual dynamic code: 
+    public final Double invoke(Map<String, ? extends Double> arguments) {
+        return (Double)((RealField)super.algebra).add((Double)arguments.get("x"), (Double)2.0D);
+    }
+}
+```
+
+### Example Usage
+
+This API is an extension to MST and MSTExpression APIs. You may optimize both MST and MSTExpression: 
+
+```kotlin
+RealField.mstInField { symbol("x") + 2 }.compile()
+RealField.expression("2+2".parseMath())
+```
+
+### Known issues
+
+- Using numeric algebras causes boxing and calling bridge methods. 
+- The same classes may be generated and loaded twice, so it is recommended to cache compiled expressions to avoid
+class loading overhead. 
+- This API is not supported by non-dynamic JVM implementations (like TeaVM and GraalVM) because of using class loaders.

 ### Known issues
 
-- Using numeric algebras causes boxing and calling bridge methods. 
 - The same classes may be generated and loaded twice, so it is recommended to cache compiled expressions to avoid
 class loading overhead. 
 - This API is not supported by non-dynamic JVM implementations (like TeaVM and GraalVM) because of using class loaders.

 Buffer is one of main building blocks of kmath. It is a basic interface allowing random-access read and write (with `MutableBuffer`).
 There are different types of buffers:
 
-* Primitive buffers wrapping like `DoubleBuffer` which are wrapping primitive arrays.
+* Primitive buffers wrapping like `RealBuffer` which are wrapping primitive arrays.
 * Boxing `ListBuffer` wrapping a list
 * Functionally defined `VirtualBuffer` which does not hold a state itself, but provides a function to calculate value
 * `MemoryBuffer` allows direct allocation of objects in continuous memory block.

+# ND4J NDStructure implementation (`kmath-nd4j`)
+
+This subproject implements the following features:
+
+- NDStructure wrapper for INDArray.
+- Optimized NDRing implementation for INDArray storing Ints.
+- Optimized NDField implementation for INDArray storing Floats and Doubles.
+
+> #### Artifact:
+> This module is distributed in the artifact `scientifik:kmath-nd4j:0.1.4-dev-8`.
+> 
+> **Gradle:**
+>
+> ```gradle
+> repositories {
+>     maven { url 'https://dl.bintray.com/mipt-npm/scientifik' }
+>     maven { url 'https://dl.bintray.com/mipt-npm/dev' }
+> }
+> 
+> dependencies {
+>     implementation 'scientifik:kmath-nd4j:0.1.4-dev-8'
+> }
+> ```
+> **Gradle Kotlin DSL:**

+> }
+> 
+> dependencies {
+>     implementation("scientifik:kmath-nd4j:0.1.4-dev-8")
+> }
+> ```
+>
+
+## Examples
+
+NDStructure wrapper for INDArray:
+
+```kotlin
+import org.nd4j.linalg.factory.*
+import scientifik.kmath.nd4j.*
+import scientifik.kmath.structures.*
+
+val array = Nd4j.ones(2, 2)!!.asRealStructure()
+println(array[0, 0]) // 1.0
+array[intArrayOf(0, 0)] = 24.0
+println(array[0, 0]) // 24.0
+```
+
+Fast element-wise arithmetics for INDArray:
+
+```kotlin
+import org.nd4j.linalg.factory.*
+import scientifik.kmath.nd4j.*
+import scientifik.kmath.operations.*
+
+val field = RealINDArrayField(intArrayOf(2, 2))
+val array = Nd4j.rand(2, 2)!!.asRealStructure()
+
+val res = field {
+    (25.0 / array + 20) * 4
+}
+
+println(res.ndArray)
+// [[  250.6449,  428.5840], 
+//  [  269.7913,  202.2077]]

-## Algebra hierarchy
+## Algebraic Structures
 
 Mathematical contexts have the following hierarchy:
 
-**Space** <- **Ring** <- **Field**
+**Algebra** � **Space** � **Ring** � **Field**
 
-All classes follow abstract mathematical constructs.
-[Space](http://mathworld.wolfram.com/Space.html) defines `zero` element, addition operation and multiplication by constant,
-[Ring](http://mathworld.wolfram.com/Ring.html) adds multiplication and unit `one` element,
-[Field](http://mathworld.wolfram.com/Field.html) adds division operation.
+These interfaces follow real algebraic structures:
 
-Typical case of `Field` is the `RealField` which works on doubles. And typical case of `Space` is a `VectorSpace`.
+- [Space](https://mathworld.wolfram.com/VectorSpace.html) defines addition, its neutral element (i.e. 0) and scalar 
+multiplication;
+- [Ring](http://mathworld.wolfram.com/Ring.html) adds multiplication and its neutral element (i.e. 1);
+- [Field](http://mathworld.wolfram.com/Field.html) adds division operation.
 
-In some cases algebra context could hold additional operation like `exp` or `sin`, in this case it inherits appropriate
-interface. Also a context could have an operation which produces an element outside of its context. For example
-`Matrix` `dot` operation produces a matrix with new dimensions which can be incompatible with initial matrix in
-terms of linear operations.

+## Spaces and Fields
 
-An obvious first choice of mathematical objects to implement in a context-oriented style are algebraic elements like spaces,
-rings and fields. Those are located in the `scientifik.kmath.operations.Algebra.kt` file. Alongside common contexts, the file includes definitions for algebra elements like `FieldElement`. A `FieldElement` object
-stores a reference to the `Field` which contains additive and multiplicative operations, meaning
-it has one fixed context attached and does not require explicit external context. So those `MathElements` can be operated without context:
+KMath submits both contexts and elements for builtin algebraic structures:
 
 ```kotlin
+import scientifik.kmath.operations.*
+
 val c1 = Complex(1.0, 2.0)
 val c2 = ComplexField.i
+
 val c3 = c1 + c2
+// or
+val c3 = ComplexField { c1 + c2 }
 ```
 
-`ComplexField` also features special operations to mix complex and real numbers, for example:

+KMath support for linear algebra organized in a context-oriented way. Meaning that operations are in most cases declared 
 in context classes, and are not the members of classes that store data. This allows more flexible approach to maintain multiple 
 back-ends. The new operations added as extensions to contexts instead of being member functions of data structures.

+## [Unreleased]
+
+### Added
+- Functional Expressions API
+- Mathematical Syntax Tree, its interpreter and API
+- String to MST parser (https://github.com/mipt-npm/kmath/pull/120)
+- MST to JVM bytecode translator (https://github.com/mipt-npm/kmath/pull/94)
+- FloatBuffer (specialized MutableBuffer over FloatArray)
+- FlaggedBuffer to associate primitive numbers buffer with flags (to mark values infinite or missing, etc.)
+- Specialized builder functions for all primitive buffers like `IntBuffer(25) { it + 1 }` (https://github.com/mipt-npm/kmath/pull/125)
+- Interface `NumericAlgebra` where `number` operation is available to convert numbers to algebraic elements
+- Inverse trigonometric functions support in ExtendedField (`asin`, `acos`, `atan`) (https://github.com/mipt-npm/kmath/pull/114)
+- New space extensions: `average` and `averageWith`
+- Local coding conventions
+- Geometric Domains API in `kmath-core`
+- Blocking chains in `kmath-coroutines`
+
+### Changed
+- BigInteger and BigDecimal algebra: JBigDecimalField has companion object with default math context; minor optimizations
+- `power(T, Int)` extension function has preconditions and supports `Field<T>`
+- Memory objects have more preconditions (overflow checking)
+- `tg` function is renamed to `tan` (https://github.com/mipt-npm/kmath/pull/114)
+- Gradle version: 6.3 -> 6.5.1
+- Moved probability distributions to commons-rng and to `kmath-prob`.
+
+### Fixed
+- Missing copy method in Memory implementation on JS (https://github.com/mipt-npm/kmath/pull/106)
+- D3.dim value in `kmath-dimensions`
+- Multiplication in integer rings in `kmath-core` (https://github.com/mipt-npm/kmath/pull/101)
+- Commons RNG compatibility (https://github.com/mipt-npm/kmath/issues/93)

Subject: [PATCH 197/956] Provide contracts for many functions, make inline
 several functions, replace <algebra>.run { and with(<algebra>> { with
 <algebra> {, add newlines at EOFs, specify operator modifier explicitly at
 many places, reformat files, replace if (...) error guards with require and
 check

 - Norm support for `Complex`
 
 ### Changed
+- `readAsMemory` now has `throws IOException` in JVM signature.
+- Several functions taking functional types were made `inline`.
+- Several functions taking functional types now have `callsInPlace` contracts.
 - BigInteger and BigDecimal algebra: JBigDecimalField has companion object with default math context; minor optimizations
 - `power(T, Int)` extension function has preconditions and supports `Field<T>`
 - Memory objects have more preconditions (overflow checking)
 - `tg` function is renamed to `tan` (https://github.com/mipt-npm/kmath/pull/114)
-- Gradle version: 6.3 -> 6.5.1
+- Gradle version: 6.3 -> 6.6
 - Moved probability distributions to commons-rng and to `kmath-prob`
 
 ### Fixed

 # Goal
 * Provide a flexible and powerful API to work with mathematics abstractions in Kotlin-multiplatform (JVM and JS for now and Native in future). 
 * Provide basic multiplatform implementations for those abstractions (without significant performance optimization).

 ## Multi-platform support
 
 KMath is developed as a multi-platform library, which means that most of interfaces are declared in the [common module](kmath-core/src/commonMain). Implementation is also done in the common module wherever possible. In some cases, features are delegated to platform-specific implementations even if they could be done in the common module for performance reasons. Currently, the JVM is the main focus of development, however Kotlin/Native and Kotlin/JS contributions are also welcome.

+# KMath
+Could be pronounced as `key-math`.
+The Kotlin MATHematics library is intended as a Kotlin-based analog to Python's `numpy` library. In contrast to `numpy` and `scipy` it is modular and has a lightweight core.
+
+## Publications
+* [A conceptual article about context-oriented design](https://proandroiddev.com/an-introduction-context-oriented-programming-in-kotlin-2e79d316b0a2)
+* [Another article about context-oriented design](https://proandroiddev.com/diving-deeper-into-context-oriented-programming-in-kotlin-3ecb4ec38814)
+* [ACAT 2019 conference paper](https://aip.scitation.org/doi/abs/10.1063/1.5130103)
+
+# Goal
+* Provide a flexible and powerful API to work with mathematics abstractions in Kotlin-multiplatform (JVM and JS for now and Native in future). 
+* Provide basic multiplatform implementations for those abstractions (without significant performance optimization).
+* Provide bindings and wrappers with those abstractions for popular optimized platform libraries.
+
+## Non-goals
+* Be like Numpy. It was the idea at the beginning, but we decided that we can do better in terms of API.
+* Provide best performance out of the box. We have specialized libraries for that. Need only API wrappers for them.
+* Cover all cases as immediately and in one bundle. We will modularize everything and add new features gradually.
+* Provide specialized behavior in the core. API is made generic on purpose, so one needs to specialize for types, like for `Double` in the core. For that we will have specialization modules like `for-real`, which will give better experience for those, who want to work with specific types.
+
+## Features
+
+Actual feature list is [here](docs/features.md)
+
+* **Algebra**
+    * Algebraic structures like rings, spaces and field (**TODO** add example to wiki)
+    * Basic linear algebra operations (sums, products, etc.), backed by the `Space` API.
+    * Complex numbers backed by the `Field` API (meaning that they will be usable in any structure like vectors and N-dimensional arrays).
+    * Advanced linear algebra operations like matrix inversion and LU decomposition.
+
+* **Array-like structures** Full support of many-dimensional array-like structures 
+including mixed arithmetic operations and function operations over arrays and numbers (with the added benefit of static type checking).
+
+* **Expressions** By writing a single mathematical expression
+once, users will be able to apply different types of objects to the expression by providing a context. Expressions
+can be used for a wide variety of purposes from high performance calculations to code generation.
+
+* **Histograms** Fast multi-dimensional histograms.
+
+* **Streaming** Streaming operations on mathematical objects and objects buffers.
+
+* **Type-safe dimensions** Type-safe dimensions for matrix operations.
+
+* **Commons-math wrapper** It is planned to gradually wrap most parts of [Apache commons-math](http://commons.apache.org/proper/commons-math/)
+                           library in Kotlin code and maybe rewrite some parts to better suit the Kotlin programming paradigm, however there is no fixed roadmap for that. Feel free
+                           to submit a feature request if you want something to be done first.
+                           
+## Planned features
+
+* **Messaging** A mathematical notation to support multi-language and multi-node communication for mathematical tasks.
+
+* **Array statistics** 
+
+* **Integration** Univariate and multivariate integration framework.
+
+* **Probability and distributions**
+
+* **Fitting** Non-linear curve fitting facilities
+
+## Modules
+

+
+## Multi-platform support
+
+KMath is developed as a multi-platform library, which means that most of interfaces are declared in the [common module](kmath-core/src/commonMain). Implementation is also done in the common module wherever possible. In some cases, features are delegated to platform-specific implementations even if they could be done in the common module for performance reasons. Currently, the JVM is the main focus of development, however Kotlin/Native and Kotlin/JS contributions are also welcome.
+
+## Performance
+
+Calculation performance is one of major goals of KMath in the future, but in some cases it is not possible to achieve both performance and flexibility. We expect to focus on creating convenient universal API first and then work on increasing performance for specific cases. We expect the worst KMath benchmarks will perform better than native Python, but worse than optimized native/SciPy (mostly due to boxing operations on primitive numbers). The best performance of optimized parts could be better than SciPy.
+
+### Dependency
+
+Release artifacts are accessible from bintray with following configuration (see documentation for [kotlin-multiplatform](https://kotlinlang.org/docs/reference/multiplatform.html) form more details):
+
+```kotlin
+repositories{
+    maven("https://dl.bintray.com/mipt-npm/kscience")
+}
+
+dependencies{
+    api("kscience.kmath:kmath-core:$version")
+    //api("kscience.kmath:kmath-core-jvm:$version") for jvm-specific version
+}
+```
+
+Gradle `6.0+` is required for multiplatform artifacts.
+
+### Development
+
+Development builds are accessible from the reposirtory 
+```kotlin
+repositories{
+    maven("https://dl.bintray.com/mipt-npm/dev")
+}
+```
+with the same artifact names.
+
+## Contributing
+
+The project requires a lot of additional work. Please feel free to contribute in any way and propose new features.

 Could be pronounced as `key-math`.
-The Kotlin MATHematics library is intended as a Kotlin-based analog to Python's `numpy` library. In contrast to `numpy` and `scipy` it is modular and has a lightweight core.
+The Kotlin MATHematics library  was initially intended as a Kotlin-based analog to Python's `numpy` library. Later we found that kotlin is much more flexible language and allows superior architecture designs. In contrast to `numpy` and `scipy` it is modular and has a lightweight core. The `numpy`-like experience could be achieved with [kmath-for-real](/kmath-for-real) extension module.

-KMath is developed as a multi-platform library, which means that most of interfaces are declared in the [common module](kmath-core/src/commonMain). Implementation is also done in the common module wherever possible. In some cases, features are delegated to platform-specific implementations even if they could be done in the common module for performance reasons. Currently, the JVM is the main focus of development, however Kotlin/Native and Kotlin/JS contributions are also welcome.

+/* In recent versiions of GCC, the inline keyword has two different
+   forms: GNU and C99.
+
+   In GNU mode we can use 'extern inline' to make inline functions
+   work like macros.  The function is only inlined--it is never output
+   as a definition in an object file.
+
+   In the new C99 mode 'extern inline' has a different meaning--it
+   causes the definition of the function to be output in each object
+   file where it is used.  This will result in multiple-definition
+   errors on linking.  The 'inline' keyword on its own (without
+   extern) has the same behavior as the original GNU 'extern inline'.
+
+   The C99 style is the default with -std=c99 in GCC 4.3.  
+
+   This header file allows either form of inline to be used by
+   redefining the macros INLINE_DECL and INLINE_FUN.  These are used
+   in the public header files as
+

-/* In recent versiions of GCC, the inline keyword has two different

-   work like macros.  The function is only inlined--it is never output
-   as a definition in an object file.
-
-   In the new C99 mode 'extern inline' has a different meaning--it

-   errors on linking.  The 'inline' keyword on its own (without
-   extern) has the same behavior as the original GNU 'extern inline'.
-
-   The C99 style is the default with -std=c99 in GCC 4.3.  
-
-   This header file allows either form of inline to be used by
-   redefining the macros INLINE_DECL and INLINE_FUN.  These are used

 # KMath
-Could be pronounced as `key-math`.
-The Kotlin MATHematics library  was initially intended as a Kotlin-based analog to Python's `numpy` library. Later we found that kotlin is much more flexible language and allows superior architecture designs. In contrast to `numpy` and `scipy` it is modular and has a lightweight core. The `numpy`-like experience could be achieved with [kmath-for-real](/kmath-for-real) extension module.

+* Provide a flexible and powerful API to work with mathematics abstractions in Kotlin-multiplatform (JVM, JS and Native). 
 * Provide basic multiplatform implementations for those abstractions (without significant performance optimization).
 * Provide bindings and wrappers with those abstractions for popular optimized platform libraries.
 
 ## Non-goals
-* Be like Numpy. It was the idea at the beginning, but we decided that we can do better in terms of API.
-* Provide best performance out of the box. We have specialized libraries for that. Need only API wrappers for them.

+* Provide the best performance out of the box. We have specialized libraries for that. Need only API wrappers for them.
 * Cover all cases as immediately and in one bundle. We will modularize everything and add new features gradually.
-* Provide specialized behavior in the core. API is made generic on purpose, so one needs to specialize for types, like for `Double` in the core. For that we will have specialization modules like `for-real`, which will give better experience for those, who want to work with specific types.

-KMath is developed as a multi-platform library, which means that most of the interfaces are declared in the [common module](/kmath-core/src/commonMain). Implementation is also done in the common module wherever possible. In some cases, features are delegated to platform-specific implementations even if they could be done in the common module for performance reasons. Currently, the JVM is the main focus of development, however Kotlin/Native and Kotlin/JS contributions are also welcome.

+feedback are also welcome.
 
 ## Performance
 
-Calculation performance is one of major goals of KMath in the future, but in some cases it is not possible to achieve both performance and flexibility. We expect to focus on creating convenient universal API first and then work on increasing performance for specific cases. We expect the worst KMath benchmarks will perform better than native Python, but worse than optimized native/SciPy (mostly due to boxing operations on primitive numbers). The best performance of optimized parts could be better than SciPy.

 # KMath
-Could be pronounced as `key-math`.
-The Kotlin MATHematics library  was initially intended as a Kotlin-based analog to Python's `numpy` library. Later we found that kotlin is much more flexible language and allows superior architecture designs. In contrast to `numpy` and `scipy` it is modular and has a lightweight core. The `numpy`-like experience could be achieved with [kmath-for-real](/kmath-for-real) extension module.

+* Provide a flexible and powerful API to work with mathematics abstractions in Kotlin-multiplatform (JVM, JS and Native). 
 * Provide basic multiplatform implementations for those abstractions (without significant performance optimization).
 * Provide bindings and wrappers with those abstractions for popular optimized platform libraries.
 
 ## Non-goals
-* Be like Numpy. It was the idea at the beginning, but we decided that we can do better in terms of API.
-* Provide best performance out of the box. We have specialized libraries for that. Need only API wrappers for them.

 * Cover all cases as immediately and in one bundle. We will modularize everything and add new features gradually.
-* Provide specialized behavior in the core. API is made generic on purpose, so one needs to specialize for types, like for `Double` in the core. For that we will have specialization modules like `for-real`, which will give better experience for those, who want to work with specific types.

+// Type definitions for ESTree AST specification
+// Project: https://github.com/estree/estree
+// Definitions by: RReverser <https://github.com/RReverser>
+// Definitions: https://github.com/DefinitelyTyped/DefinitelyTyped
+
+// This definition file follows a somewhat unusual format. ESTree allows
+// runtime type checks based on the `type` parameter. In order to explain this
+// to typescript we want to use discriminated union types:
+// https://github.com/Microsoft/TypeScript/pull/9163
+//
+// For ESTree this is a bit tricky because the high level interfaces like
+// Node or Function are pulling double duty. We want to pass common fields down
+// to the interfaces that extend them (like Identifier or
+// ArrowFunctionExpression), but you can't extend a type union or enforce
+// common fields on them. So we've split the high level interfaces into two
+// types, a base type which passes down inhereted fields, and a type union of
+// all types which extend the base type. Only the type union is exported, and
+// the union is how other types refer to the collection of inheriting types.
+//
+// This makes the definitions file here somewhat more difficult to maintain,
+// but it has the notable advantage of making ESTree much easier to use as
+// an end user.

-// Definitions: https://github.com/DefinitelyTyped/DefinitelyTyped
-
-// This definition file follows a somewhat unusual format. ESTree allows
-// runtime type checks based on the `type` parameter. In order to explain this
-// to typescript we want to use discriminated union types:
-// https://github.com/Microsoft/TypeScript/pull/9163
-//
-// For ESTree this is a bit tricky because the high level interfaces like
-// Node or Function are pulling double duty. We want to pass common fields down
-// to the interfaces that extend them (like Identifier or
-// ArrowFunctionExpression), but you can't extend a type union or enforce
-// common fields on them. So we've split the high level interfaces into two
-// types, a base type which passes down inhereted fields, and a type union of
-// all types which extend the base type. Only the type union is exported, and
-// the union is how other types refer to the collection of inheriting types.
-//
-// This makes the definitions file here somewhat more difficult to maintain,
-// but it has the notable advantage of making ESTree much easier to use as
-// an end user.

+The code above returns expression implemented with such a JS function:

+};
+```
+
+#### Known issues
+
+- This feature uses `eval` which can be unavailable in several environments.

+RealField.mstInField { symbol("x") + 2 }.compile()
+``` 
+
+… leads to generation of bytecode, which can be decompiled to the following Java class:
+
+```java
+package kscience.kmath.asm.generated;
+
+import java.util.Map;
+import kotlin.jvm.functions.Function2;
+import kscience.kmath.asm.internal.MapIntrinsics;
+import kscience.kmath.expressions.Expression;
+import kscience.kmath.expressions.Symbol;
+
+public final class AsmCompiledExpression_45045_0 implements Expression<Double> {
+    private final Object[] constants;
+
+    public final Double invoke(Map<Symbol, Double> arguments) {
+        return (Double)((Function2)this.constants[0]).invoke((Double)MapIntrinsics.getOrFail(arguments, "x"), 2);
+    }
+
+    public AsmCompiledExpression_45045_0(Object[] constants) {
+        this.constants = constants;
+    }
+}
+
+```
+
+### Example Usage
+
+This API extends MST and MstExpression, so you may optimize as both of them:
+
+```kotlin
+RealField.mstInField { symbol("x") + 2 }.compile()
+RealField.expression("x+2".parseMath())
+```
+
+#### Known issues
+
+- The same classes may be generated and loaded twice, so it is recommended to cache compiled expressions to avoid
+  class loading overhead.
+- This API is not supported by non-dynamic JVM implementations (like TeaVM and GraalVM) because of using class loaders.
+
+### On JS
+
+A similar feature is also available on JS.
+
+```kotlin
+RealField.mstInField { symbol("x") + 2 }.compile()
+``` 
+
+The code above returns expression implemented with such a JS function:
+
+```js
+var executable = function (constants, arguments) {
+  return constants[1](constants[0](arguments, "x"), 2);
+};
+```
+
+#### Known issues
+
+- This feature uses `eval` which can be unavailable in several environments.

-Current feature list is [here](/docs/features.md)
+KMath is a modular library. Different modules provide different features with different API stability guarantees. All core modules are released with the same version, but with different API change policy. The features are described in module definitions below. The module stability could have following levels:
 
-* **Algebra**

-Current feature list is [here](/docs/features.md)
+KMath is a modular library. Different modules provide different features with different API stability guarantees. All core modules are released with the same version, but with different API change policy. The features are described in module definitions below. The module stability could have following levels:
 
-* **Algebra**
-    * Algebraic structures like rings, spaces and fields (**TODO** add example to wiki)
-    * Basic linear algebra operations (sums, products, etc.), backed by the `Space` API.
-    * Complex numbers backed by the `Field` API (meaning they will be usable in any structure like vectors and

-The core features of KMath:
-
- - [algebras](src/commonMain/kotlin/kscience/kmath/operations/Algebra.kt) : Algebraic structures like rings, spaces and fields.
- - [nd](src/commonMain/kotlin/kscience/kmath/structures/NDStructure.kt) : Many-dimensional structures and operations on them.
- - [linear](src/commonMain/kotlin/kscience/kmath/operations/Algebra.kt) : Basic linear algebra operations (sums, products, etc.), backed by the `Space` API. Advanced linear algebra operations like matrix inversion and LU decomposition.
- - [buffers](src/commonMain/kotlin/kscience/kmath/structures/Buffers.kt) : One-dimensional structure
- - [expressions](src/commonMain/kotlin/kscience/kmath/expressions) : By writing a single mathematical expression once, users will be able to apply different types of 
-objects to the expression by providing a context. Expressions can be used for a wide variety of purposes from high 
-performance calculations to code generation.
- - [domains](src/commonMain/kotlin/kscience/kmath/domains) : Domains
- - [autodif](src/commonMain/kotlin/kscience/kmath/expressions/SimpleAutoDiff.kt) : Automatic differentiation

+# The Core Module (`kmath-core`)
+
+The core features of KMath:
+
+ - [algebras](src/commonMain/kotlin/kscience/kmath/operations/Algebra.kt) : Algebraic structures like rings, spaces and fields.
+ - [nd](src/commonMain/kotlin/kscience/kmath/structures/NDStructure.kt) : Many-dimensional structures and operations on them.
+ - [linear](src/commonMain/kotlin/kscience/kmath/operations/Algebra.kt) : Basic linear algebra operations (sums, products, etc.), backed by the `Space` API. Advanced linear algebra operations like matrix inversion and LU decomposition.
+ - [buffers](src/commonMain/kotlin/kscience/kmath/structures/Buffers.kt) : One-dimensional structure
+ - [expressions](src/commonMain/kotlin/kscience/kmath/expressions) : By writing a single mathematical expression once, users will be able to apply different types of 
+objects to the expression by providing a context. Expressions can be used for a wide variety of purposes from high 
+performance calculations to code generation.
+ - [domains](src/commonMain/kotlin/kscience/kmath/domains) : Domains
+ - [autodif](src/commonMain/kotlin/kscience/kmath/expressions/SimpleAutoDiff.kt) : Automatic differentiation

+A typical implementation of `Field<T>` is the `DoubleField` which works on doubles, and `VectorSpace` for `Space<T>`.
 
 In some cases algebra context can hold additional operations like `exp` or `sin`, and then it inherits appropriate
 interface. Also, contexts may have operations, which produce elements outside of the context. For example, `Matrix.dot`

- * Sampler for the Poisson distribution.
- * - For small means, a Poisson process is simulated using uniform deviates, as described in

- *   integer-valued distributions: The Poisson distribution. Addison Wesley.
- * - The Poisson process (and hence, the returned value) is bounded by 1000 * mean.
- *   This sampler is suitable for mean < 40. For large means, [LargeMeanPoissonSampler] should be used instead.

- * Based on Commons RNG implementation.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include

+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You

-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.
-
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"
-      replaced with your own identifying information. (Don't include

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-

-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to

-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and

-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally

-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,

-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and

-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS

+     * For trigonometric functions, use of look-up tables and Taylor-Lagrange formula
+     * with 4 derivatives (more take longer to compute and don't add much accuracy,
+     * less require larger tables (which use more memory, take more time to initialize,
+     * and are slower to access (at least on the machine they were developed on))).
+     *
+     * For angles reduction of cos/sin/tan functions:
+     * - for small values, instead of reducing angles, and then computing the best index
+     *   for look-up tables, we compute this index right away, and use it for reduction,
+     * - for large values, treatments derived from fdlibm package are used, as done in
+     *   java.lang.Math. They are faster but still "slow", so if you work with
+     *   large numbers and need speed over accuracy for them, you might want to use
+     *   normalizeXXXFast treatments before your function, or modify cos/sin/tan
+     *   so that they call the fast normalization treatments instead of the accurate ones.
+     *   NB: If an angle is huge (like PI*1e20), in double precision format its last digits
+     *       are zeros, which most likely is not the case for the intended value, and doing
+     *       an accurate reduction on a very inaccurate value is most likely pointless.
+     *       But it gives some sort of coherence that could be needed in some cases.
+     *
+     * Multiplication on double appears to be about as fast (or not much slower) than call
+     * to <double_array>[<index>], and regrouping some doubles in a private class, to use
+     * index only once, does not seem to speed things up, so:
+     * - for uniformly tabulated values, to retrieve the parameter corresponding to
+     *   an index, we recompute it rather than using an array to store it,
+     * - for cos/sin, we recompute derivatives divided by (multiplied by inverse of)
+     *   factorial each time, rather than storing them in arrays.
+     *
+     * Lengths of look-up tables are usually of the form 2^n+1, for their values to be
+     * of the form (<a_constant> * k/2^n, k in 0 .. 2^n), so that particular values
+     * (PI/2, etc.) are "exactly" computed, as well as for other reasons.
+     *
+     * Tables are put in specific inner classes, to be lazily initialized.
+     * Always doing strict tables initialization, even if StrictFastMath delegates
+     * to StrictMath and doesn't use tables, which makes tables initialization a bit
+     * slower but code simpler.
+     * Using redefined pure Java treatments during tables initialization,
+     * instead of Math or StrictMath ones (even asin(double)), can be very slow,
+     * because class loading is likely not to be optimized.
+     *
+     * Most math treatments I could find on the web, including "fast" ones,
+     * usually take care of special cases (NaN, etc.) at the beginning, and
+     * then deal with the general case, which adds a useless overhead for the
+     * general (and common) case. In this class, special cases are only dealt
+     * with when needed, and if the general case does not already handle them.

-     * For trigonometric functions, use of look-up tables and Taylor-Lagrange formula
-     * with 4 derivatives (more take longer to compute and don't add much accuracy,
-     * less require larger tables (which use more memory, take more time to initialize,
-     * and are slower to access (at least on the machine they were developed on))).
-     *
-     * For angles reduction of cos/sin/tan functions:
-     * - for small values, instead of reducing angles, and then computing the best index
-     *   for look-up tables, we compute this index right away, and use it for reduction,
-     * - for large values, treatments derived from fdlibm package are used, as done in
-     *   java.lang.Math. They are faster but still "slow", so if you work with
-     *   large numbers and need speed over accuracy for them, you might want to use
-     *   normalizeXXXFast treatments before your function, or modify cos/sin/tan
-     *   so that they call the fast normalization treatments instead of the accurate ones.
-     *   NB: If an angle is huge (like PI*1e20), in double precision format its last digits
-     *       are zeros, which most likely is not the case for the intended value, and doing
-     *       an accurate reduction on a very inaccurate value is most likely pointless.
-     *       But it gives some sort of coherence that could be needed in some cases.
-     *
-     * Multiplication on double appears to be about as fast (or not much slower) than call
-     * to <double_array>[<index>], and regrouping some doubles in a private class, to use
-     * index only once, does not seem to speed things up, so:
-     * - for uniformly tabulated values, to retrieve the parameter corresponding to
-     *   an index, we recompute it rather than using an array to store it,
-     * - for cos/sin, we recompute derivatives divided by (multiplied by inverse of)
-     *   factorial each time, rather than storing them in arrays.
-     *
-     * Lengths of look-up tables are usually of the form 2^n+1, for their values to be
-     * of the form (<a_constant> * k/2^n, k in 0 .. 2^n), so that particular values
-     * (PI/2, etc.) are "exactly" computed, as well as for other reasons.
-     *
-     * Tables are put in specific inner classes, to be lazily initialized.
-     * Always doing strict tables initialization, even if StrictFastMath delegates
-     * to StrictMath and doesn't use tables, which makes tables initialization a bit
-     * slower but code simpler.
-     * Using redefined pure Java treatments during tables initialization,
-     * instead of Math or StrictMath ones (even asin(double)), can be very slow,
-     * because class loading is likely not to be optimized.
-     *
-     * Most math treatments I could find on the web, including "fast" ones,
-     * usually take care of special cases (NaN, etc.) at the beginning, and
-     * then deal with the general case, which adds a useless overhead for the
-     * general (and common) case. In this class, special cases are only dealt
-     * with when needed, and if the general case does not already handle them.

 # Module kmath-jafama
 
-Jafama based implementation of DoubleField of kmath-operations.
+Integration with [Jafama](https://github.com/jeffhain/jafama).
 
-- JafamaDoubleField : DoubleField implementation using FastMath
-- StrictJafamaDoubleField - DoubleField implementation using StrictFastMath
+ - [jafama-double](src/main/kotlin/space/kscience/kmath/jafama/) : Double ExtendedField implementations based on Jafama
 
-## Examples
 
-Different Operations on DoubleField
+## Artifact:
 
+The Maven coordinates of this project are `space.kscience:kmath-jafama:0.3.0-dev-13`.
+
+**Gradle:**
+```gradle
+repositories {
+    maven { url 'https://repo.kotlin.link' }
+    mavenCentral()
+}
+
+dependencies {
+    implementation 'space.kscience:kmath-jafama:0.3.0-dev-13'
+}
+```
+**Gradle Kotlin DSL:**
 ```kotlin
-package space.kscience.kmath.jafama
+repositories {
+    maven("https://repo.kotlin.link")
+    mavenCentral()
+}
 
-import net.jafama.FastMath
-
-
-fun main(){
-    val a = JafamaDoubleField.number(2.0)
-    val b = StrictJafamaDoubleField.power(FastMath.E,a)
-    println(JafamaDoubleField.add(b,a))
-    println(StrictJafamaDoubleField.ln(b))
+dependencies {
+    implementation("space.kscience:kmath-jafama:0.3.0-dev-13")
 }
 ```
 
-## Benchmarks
-Comparing Operations on DoubleField and JafamaDoubleField 
-```bash
+## Example usage
+
+All the `DoubleField` uses can be replaced with `JafamaDoubleField` or `StrictJafamaDoubleField`.
+
+```kotlin
+import space.kscience.kmath.jafama.*
+import space.kscience.kmath.operations.*
+
+fun main() {
+    val a = 2.0
+    val b = StrictJafamaDoubleField { exp(a) }
+    println(JafamaDoubleField { b + a })
+    println(StrictJafamaDoubleField { ln(b) })
+}
+```
+
+## Performance
+
+According to benchmarking data, on Hotspot Jafama functions are 20% faster than JDK math. On GraalVM, they are slower.

+# Module kmath-jafama
+
+Integration with [Jafama](https://github.com/jeffhain/jafama).
+
+${features}
+
+${artifact}
+
+## Example usage
+
+All the `DoubleField` uses can be replaced with `JafamaDoubleField` or `StrictJafamaDoubleField`.
+
+```kotlin
+import space.kscience.kmath.jafama.*
+import space.kscience.kmath.operations.*
+
+fun main() {
+    val a = 2.0
+    val b = StrictJafamaDoubleField { exp(a) }
+    println(JafamaDoubleField { b + a })
+    println(StrictJafamaDoubleField { ln(b) })
+}
+```
+
+## Performance
+
+According to benchmarking data, on Hotspot Jafama functions are 20% faster than JDK math. On GraalVM, they are slower.

 ## Algebraic Structures
 
-Mathematical contexts have the following hierarchy:
+Primary mathematical contexts have the following hierarchy:
 
-**Algebra** � **Space** � **Ring** � **Field**
+`Field <: Ring <: Group <: Algebra`
 
 These interfaces follow real algebraic structures:
 
-- [Space](https://mathworld.wolfram.com/VectorSpace.html) defines addition, its neutral element (i.e. 0) and scalar 
-multiplication;
-- [Ring](http://mathworld.wolfram.com/Ring.html) adds multiplication and its neutral element (i.e. 1);
+- [Group](https://mathworld.wolfram.com/Group.html) defines addition, its identity element (i.e., 0) and additive
+  inverse (-x);
+- [Ring](http://mathworld.wolfram.com/Ring.html) adds multiplication and its identity element (i.e., 1);
 - [Field](http://mathworld.wolfram.com/Field.html) adds division operation.
 
 A typical implementation of `Field<T>` is the `DoubleField` which works on doubles, and `VectorSpace` for `Space<T>`.
 
 In some cases algebra context can hold additional operations like `exp` or `sin`, and then it inherits appropriate
-interface. Also, contexts may have operations, which produce elements outside of the context. For example, `Matrix.dot` 
-operation produces a matrix with new dimensions, which can be incompatible with initial matrix in terms of linear 
-operations.
-
-## Algebraic Element
-
-To achieve more familiar behavior (where you apply operations directly to mathematical objects), without involving 
-contexts KMath submits special type objects called `MathElement`. A `MathElement` is basically some object coupled to
-a mathematical context. For example `Complex` is the pair of real numbers representing real and imaginary parts,
-but it also holds reference to the `ComplexField` singleton, which allows performing direct operations on `Complex`
-numbers without explicit involving the context like:
-
-```kotlin
-import space.kscience.kmath.operations.*
-
-// Using elements
-val c1 = Complex(1.0, 1.0)
-val c2 = Complex(1.0, -1.0)
-val c3 = c1 + c2 + 3.0.toComplex()
-
-// Using context
-val c4 = ComplexField { c1 + i - 2.0 }
-```
-
-Both notations have their pros and cons.
-
-The hierarchy for algebraic elements follows the hierarchy for the corresponding algebraic structures.
-
-**MathElement** � **SpaceElement** � **RingElement** � **FieldElement**
-
-`MathElement<C>` is the generic common ancestor of the class with context.
-
-One major distinction between algebraic elements and algebraic contexts is that elements have three type 
-parameters:
-
-1. The type of elements, the field operates on.
-2. The self-type of the element returned from operation (which has to be an algebraic element).
-3. The type of the algebra over first type-parameter.
-
-The middle type is needed for of algebra members do not store context. For example, it is impossible to add a context 
-to regular `Double`. The element performs automatic conversions from context types and back. One should use context 
-operations in all performance-critical places. The performance of element operations is not guaranteed.

+operation produces a matrix with new dimensions, which can be incompatible with initial matrix in linear operations.
