Summary

MathParser - clsMathParser 4. - is a parser-evaluator for mathematical and physical string expressions.

This software, based on the original MathParser 2 developed by Leonardo Volpi , has been modified with the collaboration of Michael Ruder to extend the computation also to the physical variables like "3.5s" for 3.5 seconds and so on. In advance, a special routine has been developed to find out in which order the variables appear in a formula string. Thomas Zeutschler has kindly revised the code improving general efficiency by more than 200 % . Lieven Dossche has finally encapsulated the core in a nice, efficient and elegant class. In addition, starting from the v.3 of MathParser, Arnoud has created a sophisticated class- clsMathParserC - for complex numbers adding a large, good collection of complex functions and operators in a separate, reusable modules

This software is freeware. Have fun with it.
