Ublas :

In an application I would like to replace a few computationally
intensive functions with BLAS functions.
For example, when replacing prod(const matrix<double>&,const
matrix<double>&) with dgemm and linking with gotoblas
I get a speed increase of a factor of between 10 and 30 depending on the
platform. I tried to replace
prod(const symmetric_matrix<double>&,const matrix<double>&) with dsymm
but with no success. I just don't get the correct
results. Any suggestions?
