v2.10.0

New Features

• NumberTheory\Integer isPrime

v2.9.0

New Features

• Distance chebyshev

Improvements

• Internal build CI/CD improvements

v2.8.1

Improvements

• Internal improvements to improve conformance with static analysis tools

v2.8.0

New Features

• Matrix rowAddVector
• Matrix columnAddVector

Improvements

• Better error handling and exception message in Sequence\NonIntenger::hyperharmonic
• Internal code improvements to conform to static analysis checks

Backwards Incompatible Changes

• Helper method names changed (public abstract methods but not part of published interface)
  • NumericalDifferentiation::isTargetInPoints changed to assertTargetInPoints
  • NumericalDifferentiation::isSpacingConstant changed to assertSpacingConstant

v2.7.0

Improvements

• Improved algorithm for regularizedIncompleteBeta: Addresses issue 458
• Issue 456: Improved PHPDoc blocks: Changed "number" to "int|float"
• Added PHP 8.2 for CI test target

v2.6.0

v2.6.0 - 2022-04-10

Improvements

• Average::truncatedMean behavior at 50% trim made consistent
• PHP 8.1 compatibility improvements

Backwards Incompatible Changes

• Average::truncatedMean throws exception if trim percent greater than 50% rather than error or unpredictable results.

v2.5.0

New Features

• Special function logbeta
• Special function logGamma
• Special function logGammaCorr
• Special function stirlingError

Improvements

• Improvements in StudentT continuous distribution
• Improvements in special function gamma
• Improvements in special function beta

Bug Fixes

• Issue 393 (regularizedIncompleteBeta NAN)
• Issue 429 (Linear regression CI division by zero)

v2.4.0

New Features

• Complex Exponential (exp)
• Complex Exponentiation (pow)
• Zipf's Law Discrete Distribution
• Generalized harmonic non-integer sequence

Improvements

• Fixed Complex polarForm to compute the right values
• Fixed hyperharnomic non-integer sequence. Previously was computing the wrong thing
• Fixed how ArbitraryInterger handles pow of negative exponents

Backwards Incompatible Changes

• Complex polarForm now returns an array rather than a Complex number, as the Complex return was incorrect
• Interface to hyperharmonic non-integer sequence changed due to previous implementation being incorrect

v2.3.0

New Features

• Matrix SVD (Singular Value Decomposition)
• Polynomial companion matrix

v2.2.0

New Features

• PLS (Partial Least Squares Regression)

Improvements

• Add custom __debugInfo to NumericMatrix
