As the name suggests, it is a collection of mathematical functions ranging from simple calculation to complex numerical analysis. Math PHP library is completely independent and works straightaway. Its features includes Algebra, Arithmetic, Finance, Functions like Map and Polynomial, Information theory (Entropy), Linear Algebra (Matrix, Vector), Numbers (Arbitrary Integer, Complex, Rational), Number Theory (Integers), Numerical Analysis (Interpolation, Numerical Differentiation, Numerical Integration, Root Finding), Probability (Combinatorics, Distributions), Sequences (Basic, Advanced, Non-Integer), Set Theory, Statistics (Anova, Averages, Circulation, Correlation, Descriptive, Distance, Divergence, Distributions, Effect Size, Experiments, Kernel Density Estimation, Multivariance, Outlier, Random Variable, Regressions, Signification testing), Trigonometry. So if you're looking for all in one library for math function, well, this is the one.
