KMath Files

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

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)
• Multiplication of BigInt by scalar
