**Math::Expr - Parses mathematical expressions**

Parses mathematical expressions into a tree structure. The expressions may contain integers, real numbers, alphanumeric variable names, alphanumeric function names and most other characters might be used as operators. The operators can even be longer...

A string expression evaluated at i=0, 1, 2, etc, by Perl or a choice of evaluator modules. This is designed to take expression strings from user input though could be used for something quick from program code too. The expression syntax in the evalua...

KRYDE/Math-NumSeq-72 - 23 Jul 2016 06:49:13 GMT**Math::RPN - Perl extension for Reverse Polish Math Expression Evaluation**

The rpn function will take a scalar or list of sclars which contain an RPN expression as a set of comma delimited values and operators, and return the result or stack, depending on context. If the function is called in an array context, it will retur...

This module can take an algebraic expression, parses it and then decomposes it into a Taylor series, returning a new expression containing the first N elements. It understands expressions containing any of the operators +, -, *, / and ^ (raise to pow...

JONATHAN/Math-Calculus-TaylorSeries-0.1 - 20 Jul 2005 22:59:36 GMT**Math::Calculus::NewtonRaphson - Algebraic Newton Raphson Implementation**

This module can take an algebraic expression, parses it and then uses the Newton Raphson method to solve the it. The Newton Raphson method relies on the fact that the expression you pass in evaluates to zero where there is a solution. That is, to sol...
