Basic sparse matrix class with Matlab mxArray support.
Provides facilities to fill and read a sparse matrix without the pain in the $#! caused by Matlab's C interface.
However, there are a few things to remember:
It is not too well tested but worked so far for me. There are some more or less limited multiplication functions for goArray and other goSparseMatrix objects. Extend as needed.
To fill a mxArray with 3 values, you could do:
Make a "get all nonzero elements" method.
TEST ADD / MULT / SUBTRACT METHODS THOROUGHLY!
