matexpr-0.18 (http://www.cims.nyu.edu/~dbindel/matexpr/) matexpr is a source-to-source translator for embedding simple MATLAB-like matrix expressions in C/C++. matexpr interprets special comments in a source file and uses them to generate ordinary C code. To compile, edit make.inc and then run make. The output will be a standalone executable (matexpr) in the main directory. The user's guide (matexpr.pdf) describes matexpr in more detail; you can also look at the example subdirectory to get some idea of how matexpr is used.
