KMath

[Unreleased]

Added

  • fun annotation for SAM interfaces in library
  • Explicit public visibility for all public APIs
  • Better trigonometric and hyperbolic functions for AutoDiffField (https://github.com/mipt-npm/kmath/pull/140).
  • Automatic README generation for features (#139)
  • Native support for memory, core and dimensions
  • kmath-ejml to supply EJML SimpleMatrix wrapper.
  • A separate Symbol entity, which is used for global unbound symbol.
  • A Symbol indexing scope.
  • Basic optimization API for Commons-math.
  • Chi squared optimization for array-like data in CM
  • Fitting utility object in prob/stat

Changed

  • Package changed from scientifik to kscience.kmath.
  • Gradle version: 6.6 -> 6.6.1
  • Minor exceptions refactor (throwing IllegalArgumentException by argument checks instead of IllegalStateException)
  • Polynomial secondary constructor made function.
  • Kotlin version: 1.3.72 -> 1.4.20-M1
  • kmath-ast doesn't depend on heavy kotlin-reflect library.
  • Full autodiff refactoring based on Symbol
  • kmath-prob renamed to kmath-stat

Deprecated

Removed

  • kmath-koma module because it doesn't support Kotlin 1.4.
  • Support of legacy JS backend (we will support only IR)

Fixed

Security

[0.1.4]

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
  • Full hyperbolic functions support and default implementations within ExtendedField
  • 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 -> 6.6
  • Moved probability distributions to commons-rng and to kmath-prob
