Please stop me if I say silly things, as I barely don't know anything about
BLAS and co, but it seems like UBLAS doesn't support sparse matrix.

In fact, I am just planning to do one  "simple" operation : M *V where M is
a sparse matrix and V is a simple vector. I think there exists a BLAS
interface for sparse matrix, but how to find one library which implements
is a bit unclear to me... Is BLAS really just specification for a library of
standarts routines ?
