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...

Math::Expr::Opp  Represents one operation in the parsed expression tree
Used by the Math::Expr to represent algebraic expressions. This class represents one operation or function with a set of operands, which in turn can be other Math::Expr::Opp objects. And in that way we are able to represent entire expression. Operati...

Math::Expr::Rule  Represents a agebraic rule
This will create a rule that converts the expression $from to $to, and then apply that rule to $expr. $from, $to, $expr are all Math::Expr::Opp structures that should be Simplified to work ok. The result is a array @res of Math::Expr::Opp objects whi...

Math::Expr::Node  A node in the expretion tree, used as superclass only
Each expretion is represented by a tree where each opperation and variable is a separate node. This class contain the common code for all those noeds. It also defines all the common methods used in those node classes and does some typecheckinig for t...

Math::NumSeq::Expression  mathematical expression values
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...

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...

Math::Calculus::TaylorSeries  Decomposition of an expression into its Taylor Series
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...

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...

Math::Calculus::Differentiate  Algebraic Differentiation Engine
This module can take an algebraic expression, parse it into a tree structure, modify the tree to give a representation of the differentiated function, simplify the tree and turn the tree back into an output of the same form as the input. It supports ...
