<h1>muParser - a fast math parser library</h1>
<p>
Many applications require the parsing of mathematical expressions.
The main objective of this project is to provide a fast and easy way of
doing this. <b>muParser</b> is an extensible high performance math parser
library. It is based on transforming an expression into a bytecode and
precalculating constant parts of it.
</p>
<p>
<div align="center">
<img src="images/mathparser.jpg" alt="math parser logo" border="0">
</diV>
</p>
<p>
The math parser library is written in pure C++ and should compile on every
standard compliant compiler. I provide you with static libraries and a DLL
version ready for implementation into your projects. The code has been tested
using MS VC++ V7.1 and GCC V3.3.1. It reportedly works on BCB too.
I provide you with three demo projects in order to help you understand its
usage.
</p>
<p>
But before I go on, I'd like to thank SourceForge for hosting this project. This
pages would not exist without the webspace provided by them and of course I'd like
to thank CodeProject for hosting the original <a href="http://www.codeproject.com/cpp/FastMathParser.asp" target="_blank">math parser</a> article.

<br/>
The version 1.25 of muParser has been released. Unix users will find this new version much more user-friendly as it includes a standard configure script and provides a pkg-config template files which allows to easily build
applications which depend from muParser.
