The webpage was last updated in 1999!

Must be mature.

and except for the mex wrapper for MATLAB the code is from 1987. Hence no LAPACK, it has its own BLAS, LINPACK and SVD solver. However, it works fine but segfaults if I try to use vecLib or openBLAS. I have a version packaged which works like the MATLAB version according to the example on the webpage. Unfortunately it is a Mac/Linux only version because I don't know how to run the Makefile on Windows.

We can reopen this if necessary.
