LAPACK/ScaLAPACK Development

Dear All,

I hardly know anything about what scalapack and lapack do, but I need an expert to guide me to find the best starting point.

I have a matrix, G, which is very big and I want to calculate e^G. Is it possible to use scalapck for such a calculation?

Thanks in advance for your guide.

Regards,

I assume that your matrix is sparse being very large,
in which case See Expokit...

This uses a Krylov subspace technique which is likely to be the most efficient
in such cases.
