sci-mathematics FreeMat is an open sources environment for rapid engineering and scientific prototyping and data processing. It is similar to commercial systems such as MATLAB from Mathworks. FreeMat includes a codeless interface to external C/C++/FORTRAN code, parallel/distributed algorithm development (via MPI), and plotting and visualization capabilities. Add sparse eigen value support via sci-libs/arpack Enable use of dev-libs/ffcall Add sparse solving via sci-libs/umfpack
