-# KMath
-
-Could be pronounced as `key-math`. The **K**otlin **Math**ematics 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.
-
-[Documentation site](https://SciProgCentre.github.io/kmath/)

-# Goal
-
-* Provide a flexible and powerful API to work with mathematics abstractions in Kotlin-multiplatform (JVM, JS, Native and
-  Wasm).
-* 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 API.
-* 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 `kmath-for-real`, which will give better
-  experience for those, who want to work with specific types.
-
-## Features and stability
-
-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 the following levels:
-
-* **PROTOTYPE**. On this level there are no compatibility guarantees. All methods and classes form those modules could
-  break any moment. You can still use it, but be sure to fix the specific version.
-* **EXPERIMENTAL**. The general API is decided, but some changes could be made. Volatile API is marked
-  with `@UnstableKMathAPI` or other stability warning annotations.
-* **DEVELOPMENT**. API breaking generally follows semantic versioning ideology. There could be changes in minor
-  versions, but not in patch versions. API is protected
-  with [binary-compatibility-validator](https://github.com/Kotlin/binary-compatibility-validator) tool.
-* **STABLE**. The API stabilized. Breaking changes are allowed only in major releases.

-## Multi-platform support
-
-KMath is developed as a multi-platform library, which means that most of the interfaces are declared in the
-[common source sets](/kmath-core/src/commonMain) and implemented there wherever it is possible. In some cases, features
-are delegated to platform-specific implementations even if they could be provided in the common module for performance
-reasons. Currently, Kotlin/JVM is the primary platform, however, Kotlin/Native and Kotlin/JS contributions and
-feedback are also welcome.
-
-## Performance
-
-Calculation of performance is one of the major goals of KMath in the future, but in some cases it is impossible to
-achieve both
-performance and flexibility.
-
-We expect to focus on creating a 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.
-
-## Requirements
-
-KMath currently relies on JDK 11 for compilation and execution of Kotlin-JVM part. We recommend using GraalVM-CE or
-Oracle GraalVM for execution to get better performance.
-
-### Repositories
-
-Release and development artifacts are accessible from mipt-npm [Space](https://www.jetbrains.com/space/)
-repository `https://maven.pkg.jetbrains.space/mipt-npm/p/sci/maven` (see documentation of
-[Kotlin Multiplatform](https://kotlinlang.org/docs/reference/multiplatform.html) for more details). The repository could
-be reached through [repo.kotlin.link](https://repo.kotlin.link) proxy:
-
-```kotlin
-repositories {
-    maven("https://repo.kotlin.link")
-}
-
-dependencies {
-    api("space.kscience:kmath-core:$version")
-    // api("space.kscience:kmath-core-jvm:$version") for jvm-specific version
-}
-```
-
-## Contributing
-
-The project requires a lot of additional work. The most important thing we need is feedback about what features are
-required the most. Feel free to create feature requests. We are also welcome to code contributions, especially in issues
-marked
-with [good first issue](hhttps://github.com/SciProgCentre/kmath/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22)

-# Algebraic Structures and Algebraic Elements
-
-The mathematical operations in KMath are generally separated from mathematical objects. This means that to perform an
-operation, say `+`, one needs two objects of a type `T` and an algebra context, which draws appropriate operation up,
-say `Group<T>`. Next one needs to run the actual operation in the context:
-
-```kotlin
-import space.kscience.kmath.operations.*
-
-val a: T = ...
-val b: T = ...
-val group: Group<T> = ...
-
-val c = group { a + b }
-```
-
-At first glance, this distinction seems to be a needless complication, but in fact one needs to remember that in
-mathematics, one could draw up different operations on same objects. For example, one could use different types of
-geometry for vectors.
-
-## Algebraic Structures
-
-Primary mathematical contexts have the following hierarchy:
-
-`Field <: Ring <: Group <: Algebra`
-
-These interfaces follow real algebraic structures:
-
- [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 the context. For example, `Matrix.dot`
-operation produces a matrix with new dimensions, which can be incompatible with initial matrix in linear operations.
-
-## Spaces and Fields
-
-KMath introduces contexts for builtin algebraic structures:
-
-```kotlin
-import space.kscience.kmath.operations.*
-
-val c1 = Complex(1.0, 2.0)
-val c2 = ComplexField.i
-
-val c3 = c1 + c2
-// or
-val c3 = ComplexField { c1 + c2 }
-```
-
-Also, `ComplexField` features special operations to mix complex and real numbers, for example:
-
-```kotlin
-import space.kscience.kmath.operations.*
-
-val c1 = Complex(1.0, 2.0)
-val c2 = ComplexField { c1 - 1.0 } // Returns: Complex(re=0.0, im=2.0)
-val c3 = ComplexField { c1 - i * 2.0 }
-```
-
-**Note**: In theory it is possible to add behaviors directly to the context, but as for now Kotlin does not support
-that. Watch [KT-10468](https://youtrack.jetbrains.com/issue/KT-10468) and
-[KEEP-176](https://github.com/Kotlin/KEEP/pull/176) for updates.
-
-## Nested fields
-
-Contexts allow one to build more complex structures. For example, it is possible to create a `Matrix` from complex
-elements like so:
-
-```kotlin
-val element = NDElement.complex(shape = intArrayOf(2, 2)) { index: IntArray ->
-    Complex(index[0].toDouble() - index[1].toDouble(), index[0].toDouble() + index[1].toDouble())
-}
-```
-
-The `element` in this example is a member of the `Field` of 2D structures, each element of which is a member of its own
-`ComplexField`. It is important one does not need to create a special n-d class to hold complex numbers and implement
-operations on it, one just needs to provide a field for its elements.
-
-**Note**: Fields themselves do not solve the problem of JVM boxing, but it is possible to solve with special contexts
-like
-`MemorySpec`.

-# Buffers
-
-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.
-* 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.
-
-Some kmath features require a `BufferFactory` class to operate properly. A general convention is to use functions
-defined in
-`Buffer` and `MutableBuffer` companion classes. For example factory `Buffer.Companion::auto` in most cases creates the
-most suitable buffer for given reified type (for types with custom memory buffer it still better to use their
-own `MemoryBuffer.create()` factory).
-
-## Buffer performance
-
-One should avoid using default boxing buffer wherever it is possible. Try to use primitive buffers or memory buffers
-instead.

-# Coding Conventions
-
-Generally, KMath code follows
-general [Kotlin coding conventions](https://kotlinlang.org/docs/reference/coding-conventions.html), but with a number of
-small changes and clarifications.
-
-## Utility Class Naming
-
-Filename should coincide with a name of one of the classes contained in the file or start with small letter and describe
-its contents.
-
-The code convention [here](https://kotlinlang.org/docs/reference/coding-conventions.html#source-file-names) says that
-file names should start with a capital letter even if file does not contain classes. Yet starting utility classes and
-aggregators with a small letter seems to be a good way to visually separate those files.
-
-This convention could be changed in future in a non-breaking way.
-
-## Private Variable Naming
-
-Private variables' names may start with underscore `_` for of the private mutable variable is shadowed by the public
-read-only value with the same meaning.
-
-This rule does not permit underscores in names, but it is sometimes useful to "underscore" the fact that public and
-private versions draw up the same entity. It is allowed only for private variables.
-
-This convention could be changed in future in a non-breaking way.
-
-## Functions and Properties One-liners
-
-Use one-liners when they occupy single code window line both for functions and properties with getters like
-`val b: String get() = "fff"`. The same should be performed with multiline expressions when they could be
-cleanly separated.
-
-There is no universal consensus whenever use `fun a() = ...` or `fun a() { return ... }`. Yet from reader outlook
-one-lines seem to better show that the property or function is easily calculated.

-# Context-oriented mathematics
-
-## The problem
-
-A known problem for implementing mathematics in statically-typed languages (but not only in them) is that different sets
-of mathematical operators can be defined on the same mathematical objects. Sometimes there is no single way to treat
-some operations, including basic arithmetic operations, on a Java/Kotlin `Number`. Sometimes there are different ways to
-define the same structure, such as Euclidean and elliptic geometry vector spaces over real vectors. Another problem
-arises when one wants to add some kind of behavior to an existing entity. In dynamic languages those problems are
-usually solved by adding dynamic context-specific behaviors at runtime, but this solution has a lot of drawbacks.
-
-## Context-oriented approach
-
-One possible solution to these problems is to divorce numerical representations from behaviors. For example in Kotlin
-one can define a separate class representing some entity without any operations, ex. a complex number:
-
-```kotlin
-data class Complex(val re: Double, val im: Double)
-```
-
-And then to define a separate class or singleton, representing an operation on those complex numbers:
-
-```kotlin
-object ComplexOperations {
-    operator fun Complex.plus(other: Complex) = Complex(re + other.re, im + other.im)
-    operator fun Complex.minus(other: Complex) = Complex(re - other.re, im - other.im)
-}
-```
-
-In Java, applying such external operations could be cumbersome, but Kotlin has a unique feature that allows us
-implement this
-naturally: [extensions with receivers](https://kotlinlang.org/docs/reference/extensions.html#extension-functions). In
-Kotlin, an operation on complex number could be implemented as:
-
-```kotlin
-with(ComplexOperations) { c1 + c2 - c3 }
-```
-
-Kotlin also allows the creation of functions with receivers:
-
-```kotlin
-fun ComplexOperations.doSomethingWithComplex(c1: Complex, c2: Complex, c3: Complex) = c1 + c2 - c3
-
-ComplexOperations.doComethingWithComplex(c1, c2, c3)
-```
-
-In fact, whole parts of a program may be run within a mathematical context or even multiple nested contexts.
-
-In KMath, contexts are not only responsible for operations, but also for raw object creation and advanced features.
-
-## Other possibilities
-
-### Type classes
-
-An obvious candidate to get more or less the same functionality is the type class, which allows one to bind a behavior
-to a specific type without modifying the type itself. On the plus side, type classes do not require explicit context
-declaration, so the code looks cleaner. On the minus side, if there are different sets of behaviors for the same types,
-it is impossible to combine them into one module. Also, unlike type classes, context can have parameters or even state.
-For example in KMath, sizes and strides for `NDElement` or `Matrix` could be moved to context to optimize performance in
-case of a large amount of structures.
-
-### Wildcard imports and importing-on-demand
-
-Sometimes, one may wish to use a single context throughout a file. In this case, is possible to import all members from
-a package or file, via `import context.complex.*`. Effectively, this is the same as enclosing an entire file with a
-single context. However, when using multiple contexts, this technique can introduce operator ambiguity, due to namespace
-pollution. If there are multiple scoped contexts that define the same operation, it is still possible to import
-specific operations as needed, without using an explicit context with extension functions, for example:
-
-```
-import context.complex.op1
-import context.quaternion.op2
-```

-# Expressions
-
-Expressions is a feature, which allows constructing lazily or immediately calculated parametric mathematical
-expressions.
-
-The potential use-cases for it (so far) are following:
-
-* lazy evaluation (in general simple lambda is better, but there are some border cases);
-* automatic differentiation in single-dimension and in multiple dimensions;
-* generation of mathematical syntax trees with subsequent code generation for other languages;
-* symbolic computations, especially differentiation (and some other actions with `kmath-symja` integration with
-  Symja's `IExpr`&mdash;integration, simplification, and more);
-* visualization with `kmath-jupyter`.
-
-The workhorse of this API is `Expression` interface, which exposes
-single `operator fun invoke(arguments: Map<Symbol, T>): T`
-method. `ExpressionAlgebra` is used to generate expressions and introduce variables.
-
-Currently there are two implementations:
-
-* Generic `ExpressionField` in `kmath-core` which allows construction of custom lazy expressions
-
-* Auto-differentiation expression in `kmath-commons` module allows using full power of `DerivativeStructure`
-  from commons-math. **TODO: add example**

-## Basic linear algebra layout
-
-KMath support for linear algebra organized in a context-oriented way, which means 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.
-
-The main context for linear algebra over matrices and vectors is `LinearSpace`, which defines addition and dot products
-of matrices and vectors:
-
-```kotlin
-import space.kscience.kmath.linear.*
-
-LinearSpace.Companion.real {
-    val vec = buildVector(10) { i -> i.toDouble() }
-    val mat = buildMatrix(10, 10) { i, j -> i.toDouble() + j }
-
-    // Addition
-    vec + vec
-    mat + mat
-
-    // Multiplication by scalar
-    vec * 2.0
-    mat * 2.0
-
-    // Dot product
-    mat dot vec
-    mat dot mat

-# ND-structure generation and operations
-
-**TODO**
-
-# Performance for n-dimensional structures operations
-
-One of the most sought after features of mathematical libraries is the high-performance operations on n-dimensional
-structures. In `kmath` performance depends on which particular context was used for operation.
-
-Let us consider following contexts:
-
-```kotlin
-    // automatically build context most suited for given type.
-    val autoField = NDField.auto(DoubleField, dim, dim)
-    // specialized nd-field for Double. It works as generic Double field as well.
-    val specializedField = NDField.real(dim, dim)
-    //A generic boxing field. It should be used for objects, not primitives.
-    val genericField = NDField.buffered(DoubleField, dim, dim)
-```
-
-Now let us perform several tests and see, which implementation is best suited for each case:
-
-## Test case
-
-To test performance we will take 2d-structures with `dim = 1000` and add a structure filled with `1.0`
-to it `n = 1000` times.
-
-## Specialized
-
-The code to run this looks like:
-
-```kotlin
-    specializedField.run {
-        var res: NDBuffer<Float64> = one
-        repeat(n) {
-            res += 1.0
-        }
-    }
-```
-
-The performance of this code is the best of all tests since it inlines all operations and is specialized for operation
-with doubles. We will measure everything else relative to this one, so time for this test will be `1x` (real time
-on my computer is about 4.5 seconds). The only problem with this approach is that it requires specifying type
-from the beginning. Everyone does so anyway, so it is the recommended approach.
-
-## Automatic
-
-Let's do the same with automatic field inference:
-
-```kotlin
-    autoField.run {
-        var res = one
-        repeat(n) {
-            res += 1.0
-        }
-    }
-```
-
-Ths speed of this operation is approximately the same as for specialized case since `NDField.auto` just
-returns the same `RealNDField` in this case. Of course, it is usually better to use specialized method to be sure.
-
-## Lazy
-
-Lazy field does not produce a structure when asked, instead it generates an empty structure and fills it on-demand
-using coroutines to parallelize computations.
-When one calls
-
-```kotlin
-    lazyField.run {
-        var res = one
-        repeat(n) {
-            res += 1.0
-        }
-    }
-```
-
-The result will be calculated almost immediately but the result will be empty. To get the full result
-structure one needs to call all its elements. In this case computation overhead will be huge. So this field never
-should be used if one expects to use the full result structure. Though if one wants only small fraction, it could
-save a lot of time.
-
-This field still could be used with reasonable performance if call code is changed:
-
-```kotlin
-    lazyField.run {
-        val res = one.map {
-            var c = 0.0
-            repeat(n) {
-                c += 1.0
-            }
-            c
-        }
-
-        res.elements().forEach { it.second }
-    }
-```
-
-In this case it completes in about `4x-5x` time due to boxing.
-
-## Boxing
-
-The boxing field produced by
-
-```kotlin
-    genericField.run {
-        var res: NDBuffer<Float64> = one
-        repeat(n) {
-            res += 1.0
-        }
-    }
-```
-
-is the slowest one, because it requires boxing and unboxing the `double` on each operation. It takes about
-`15x` time (**TODO: there seems to be a problem here, it should be slow, but not that slow**). This field should
-never be used for primitives.
-
-## Element operation
-
-Let us also check the speed for direct operations on elements:
-
-```kotlin
-    var res = genericField.one
-    repeat(n) {
-        res += 1.0
-    }
-```
-
-One would expect to be at least as slow as field operation, but in fact, this one takes only `2x` time to complete.
-It happens, because in this particular case it does not use actual `NDField` but instead calculated directly
-via extension function.
-
-## What about python?
-
-Usually it is bad idea to compare the direct numerical operation performance in different languages, but it hard to
-work completely without frame of reference. In this case, simple numpy code:
-
-```python
-import numpy as np
-
-res = np.ones((1000,1000))
-for i in range(1000):
-    res = res + 1.0
-```
-
-gives the completion time of about `1.1x`, which means that specialized kotlin code in fact is working faster (I think
-it is
-because better memory management). Of course if one writes `res += 1.0`, the performance will be different,
-but it would be different case, because numpy overrides `+=` with in-place operations. In-place operations are
-available in `kmath` with `MutableNDStructure` but there is no field for it (one can still work with mapping
-functions).

-# Polynomials and Rational Functions
-
-KMath provides a way to work with uni- and multivariate polynomials and rational functions. It includes full support of
-arithmetic operations of integers, **constants** (elements of ring polynomials are build over), variables (for certain
-multivariate implementations), polynomials and rational functions encapsulated in so-called **polynomial space** and *
-*rational function space** and some other utilities such as algebraic differentiation and substitution.
-
-## Concrete realizations
-
-There are 3 approaches to represent polynomials:
-
-1. For univariate polynomials one can represent and store polynomial as a list of coefficients for each power of the
-   variable. I.e. polynomial $a_0 + \dots + a_n x^n $ can be represented as a finite sequence $(a_0; \dots; a_n)$. (
-   Compare to sequential definition of polynomials.)
-2. For multivariate polynomials one can represent and store polynomial as a matching (in programming it is called "map"
-   or "dictionary", in math it is
-   called [functional relation](https://en.wikipedia.org/wiki/Binary_relation#Special_types_of_binary_relations)) of
-   each "**term signature**" (that describes what variables and in what powers appear in the term) with corresponding
-   coefficient of the term. But there are 2 possible approaches of term signature representation:
-    1. One can number all the variables, so term signature can be represented as a sequence describing powers of the
-       variables. I.e. signature of term $c \\; x_0^{d_0} \dots x_n^{d_n} $ (for natural or zero $d_i $) can be
-       represented as a finite sequence $(d_0; \dots; d_n)$.
-    2. One can represent variables as objects ("**labels**"), so term signature can be also represented as a matching of
-       each appeared variable with its power in the term. I.e. signature of term $c \\; x_0^{d_0} \dots x_n^{d_n} $ (for
-       natural non-zero $d_i $) can be represented as a finite matching $(x_0 \to d_1; \dots; x_n \to d_n)$.
-
-All that three approaches are implemented by "list", "numbered", and "labeled" versions of polynomials and polynomial
-spaces respectively. Whereas all rational functions are represented as fractions with corresponding polynomial numerator
-and denominator, and rational functions' spaces are implemented in the same way as usual field of rational numbers (or
-more precisely, as any field of fractions over integral domain) should be implemented.
-
-So here are a bit of details. Let `C` by type of constants. Then:
-
-1. `ListPolynomial`, `ListPolynomialSpace`, `ListRationalFunction` and `ListRationalFunctionSpace` implement the first
-   scenario. `ListPolynomial` stores polynomial $a_0 + \dots + a_n x^n $ as a coefficients
-   list `listOf(a_0, ..., a_n)` (of type `List<C>`).
-
-   They also have variation `ScalableListPolynomialSpace` that replaces former polynomials and
-   implements `ScaleOperations`.
-2. `NumberedPolynomial`, `NumberedPolynomialSpace`, `NumberedRationalFunction` and `NumberedRationalFunctionSpace`
-   implement second scenario. `NumberedPolynomial` stores polynomials as structures of type `Map<List<UInt>, C>`.
-   Signatures are stored as `List<UInt>`. To prevent ambiguity signatures should not end with zeros.
-3. `LabeledPolynomial`, `LabeledPolynomialSpace`, `LabeledRationalFunction` and `LabeledRationalFunctionSpace` implement
-   third scenario using common `Symbol` as variable type. `LabeledPolynomial` stores polynomials as structures of
-   type `Map<Map<Symbol, UInt>, C>`. Signatures are stored as `Map<Symbol, UInt>`. To prevent ambiguity each signature
-   should not map any variable to zero.
-
-### Example: `ListPolynomial`
-
-For example, polynomial $2 - 3x + x^2 $ (with `Int` coefficients) is represented
-
-```kotlin
-val polynomial: ListPolynomial<Int> = ListPolynomial(listOf(2, -3, 1))
-// or
-val polynomial: ListPolynomial<Int> = ListPolynomial(2, -3, 1)
-```
-
-All algebraic operations can be used in corresponding space:
-
-```kotlin
-val computationResult = Int.algebra.listPolynomialSpace {
-   ListPolynomial(2, -3, 1) + ListPolynomial(0, 6) == ListPolynomial(2, 3, 1)
-}
-
-println(computationResult) // true
-```
-
-For more see [examples](../examples/src/main/kotlin/space/kscience/kmath/functions/polynomials.kt).
-
-### Example: `NumberedPolynomial`
-
-For example, polynomial $3 + 5 x_1 - 7 x_0^2 x_2 $ (with `Int` coefficients) is represented
-
-```kotlin
-val polynomial: NumberedPolynomial<Int> = NumberedPolynomial(
-   mapOf(
-      listOf<UInt>() to 3,
-      listOf(0u, 1u) to 5,
-      listOf(2u, 0u, 1u) to -7,
-   )
-)
-// or

-   listOf<UInt>() to 3,
-   listOf(0u, 1u) to 5,
-   listOf(2u, 0u, 1u) to -7,
-)
-```
-
-All algebraic operations can be used in corresponding space:
-
-```kotlin
-val computationResult = Int.algebra.numberedPolynomialSpace {
-   NumberedPolynomial(
-      listOf<UInt>() to 3,
-      listOf(0u, 1u) to 5,
-      listOf(2u, 0u, 1u) to -7,
-   ) + NumberedPolynomial(
-      listOf(0u, 1u) to -5,
-      listOf(0u, 0u, 0u, 4u) to 4,
-   ) == NumberedPolynomial(
-      listOf<UInt>() to 3,
-      listOf(0u, 1u) to 0,

-There are implemented `Polynomial` and `RationalFunction` interfaces as abstractions of polynomials and rational
-functions respectively (although, there is not a lot of logic in them) and `PolynomialSpace`
-and `RationalFunctionSpace` (that implement `Ring` interface) as abstractions of polynomials' and rational functions'
-spaces respectively. More precisely, that means they allow to declare common logic of interaction with such objects and
-spaces:
-
- `Polynomial` does not provide any logic. It is marker interface.
- `RationalFunction` provides numerator and denominator of rational function and destructuring declaration for them.
- `PolynomialSpace` provides all possible arithmetic interactions of integers, constants (of type `C`), and
-  polynomials (of type `P`) like addition, subtraction, multiplication, and some others and common properties like
-  degree of polynomial.
- `RationalFunctionSpace` provides the same as `PolynomialSpace` but also for rational functions: all possible
-  arithmetic interactions of integers, constants (of type `C`), polynomials (of type `P`), and rational functions (of
-  type `R`) like addition, subtraction, multiplication, division (in some cases), and some others and common properties
-  like degree of polynomial.
-
-Then to add abstraction of similar behaviour with variables (in multivariate case) there are
-implemented `MultivariatePolynomialSpace` and `MultivariateRationalFunctionSpace`. They just include variables (of
-type `V`) in the interactions of the entities.
-
-Also, to remove boilerplates there were provided helping subinterfaces and abstract subclasses:
-
- `PolynomialSpaceOverRing` allows to replace implementation of interactions of integers and constants with
-  implementations from provided ring over constants (of type `A: Ring<C>`).
- `RationalFunctionSpaceOverRing` &mdash; the same but for `RationalFunctionSpace`.
- `RationalFunctionSpaceOverPolynomialSpace` &mdash; the same but "the inheritance" includes interactions with
-  polynomials from provided `PolynomialSpace`.
- `PolynomialSpaceOfFractions` is actually abstract subclass of `RationalFunctionSpace` that implements all fractions
-  boilerplates with provided (`protected`) constructor of rational functions by polynomial numerator and denominator.
- `MultivariateRationalFunctionSpaceOverMultivariatePolynomialSpace` and `MultivariatePolynomialSpaceOfFractions`
-  &mdash; the same stories of operators inheritance and fractions boilerplates respectively but in multivariate case.
-
-## Utilities
-
-For all kinds of polynomials there are provided (implementation details depend on kind of polynomials) such common
-utilities as:
-
-1. differentiation and anti-differentiation,
-2. substitution, invocation and functional representation.

-# KMath
-
-Could be pronounced as `key-math`. The **K**otlin **Math**ematics 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.

-# Goal
-
-* Provide a flexible and powerful API to work with mathematics abstractions in Kotlin-multiplatform (JVM, JS, Native and
-  Wasm).
-* 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 API.
-* 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 `kmath-for-real`, which will give better
-  experience for those, who want to work with specific types.
-
-## Features and stability
-
-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 the following levels:
-
-* **PROTOTYPE**. On this level there are no compatibility guarantees. All methods and classes form those modules could
-  break any moment. You can still use it, but be sure to fix the specific version.
-* **EXPERIMENTAL**. The general API is decided, but some changes could be made. Volatile API is marked
-  with `@UnstableKMathAPI` or other stability warning annotations.
-* **DEVELOPMENT**. API breaking generally follows semantic versioning ideology. There could be changes in minor
-  versions, but not in patch versions. API is protected
-  with [binary-compatibility-validator](https://github.com/Kotlin/binary-compatibility-validator) tool.
-* **STABLE**. The API stabilized. Breaking changes are allowed only in major releases.
-
-## Modules
-
-${modules}
-
-## Multi-platform support
-
-KMath is developed as a multi-platform library, which means that most of the interfaces are declared in the
-[common source sets](/kmath-core/src/commonMain) and implemented there wherever it is possible. In some cases, features
-are delegated to platform-specific implementations even if they could be provided in the common module for performance
-reasons. Currently, Kotlin/JVM is the primary platform, however, Kotlin/Native and Kotlin/JS contributions and
-feedback are also welcome.
-
-## Performance
-
-Calculation of performance is one of the major goals of KMath in the future, but in some cases it is impossible to
-achieve both
-performance and flexibility.
-
-We expect to focus on creating a 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.
-
-## Requirements
-
-KMath currently relies on JDK 11 for compilation and execution of Kotlin-JVM part. We recommend using GraalVM-CE or
-Oracle GraalVM for execution to get better performance.
-
-### Repositories
-
-Release and development artifacts are accessible from mipt-npm [Space](https://www.jetbrains.com/space/)
-repository `https://maven.pkg.jetbrains.space/mipt-npm/p/sci/maven` (see documentation of
-[Kotlin Multiplatform](https://kotlinlang.org/docs/reference/multiplatform.html) for more details). The repository could
-be reached through [repo.kotlin.link](https://repo.kotlin.link) proxy:
-
-```kotlin

-    // api("${group}:kmath-core-jvm:$version") for jvm-specific version
-}
-```
-
-## Contributing
-
-The project requires a lot of additional work. The most important thing we need is feedback about what features are
-required the most. Feel free to create feature requests. We are also welcome to code contributions, especially in issues
-marked

-    // Other values are unused which does not make any problem to us.
-    // But in the case the corresponding value is not provided,
-    // we cannot bind the variable. Thus, exception is thrown.
-
-    // There is also a function `bindSymbolOrNull` that fixes the problem:
-    val fixedExpression = Double.autodiff.differentiate {
-        val x = bindSymbolOrNull(x) ?: const(8.0)
-        x pow -2
-    }
-    println(fixedExpression())
-    // >>> 0.015625
-    // It works!
-
-    // The expression provides a bunch of operations:
-    // 1. Constant bindings (via `const` and `number`).
-    // 2. Variable bindings (via `bindVariable`, `bindVariableOrNull`).
-    // 3. Arithmetic operations (via `+`, `-`, `*`, and `-`).
-    // 4. Exponentiation (via `pow` or `power`).
-    // 5. `exp` and `ln`.
-    // 6. Trigonometrical functions (`sin`, `cos`, `tan`, `cot`).
