Matrix new is an enhanced version of the Matrix class originally written by Diego Carrera. The script is designed to allow matrix operations in PHP code. This version introduces functions to set the matrix columns and rows values directly, added a few more mathematical functions to initialize the values of the matrix, among other enhancements.Requirements: PHP 4 or higher

This class can be used to manipulate a list of entries in a string of separated values. It can perform several operations on the list of values string like adding a set of values, importing the list from a compressed file, export the list, add, remove and update entries, search for values, etc.. Requirements: PHP 5.0 or Higher

Rational numbers are those numbers that can be represented as the ratio between two integer numbers. Any real number with a finite number decimal digits or that repeats a sequence of digits can be represented as a rational number.Adding, subtracting, multiplying and dividing are supported operations.The results of the operations are also rational numbers, simplified to eliminate any common factors ...

Mathematical expressions with operands and operators in reverse Polish can be parsed and evaluated. If the expression is split in multiple lines, it can evaluate each line individually.Currently Simple RPN Interpretersupports the operators: +,  , *, /, IF, THEN, SWAP, DUP, =, <>, >, <. >= and <= .Requirements: PHP 4.0.0 or higher

Several types of simple polynomial operations such as multiplying, dividing and removing brackets, are supported.Requirements: PHP 3.0 or higher

Render formula can be use to render mathematical formulas as graphical images. It parses a formula with constant and variable values combined with several possible mathematical operations.Currently Render formula supports formulates using the operations: addition, subtraction, multiplication, division, and functions like square root, sin arc sin, cosine, and power.Then Render formula renders the given formula in an GD library image. ...
