An open-source XML based simulation package From Ordinary Differential Equations (ODEs) up to stochastic Partial Differential Equations (PDEs) Many applications: physics mathematics engineering finance economics chemistry theoretical biology Generates fast, C++ compiled code Documentation and source are free! Runs on Linux, Unix, MacOS X and Cygwin (Windows)

XMDS is a code generator that integrates equations. You write them down in human readable form in an XML file, and it goes away and writes and compiles a C++ program that integrates those equations as fast as it can possibly be done in your architecture.
