We currently use MSVC 2008: Microsoft stopped distributing Fortran compilers ages ago and using gfortran as an extra dependency makes things too complex. I think we could use Boost's ublas for the Matrix operations and that should be sufficient for the very basic matrix support Calc provides. I am not very good with how Matrices work on C++ though, so I don't have plans to work on it. > > So - depending on BLAS, LAPACK and OpenBLAS in the future > are very good idea, and provides far better functionality and performance > without > license issues.

There are some really cool scientific packages in FORTRAN like MUMPS: http://graal.ens-lyon.fr/MUMPS/ Cheers, Pedro.
