Re: [Freepooma-devel] Sparse matrix

[Carolina Simões Gomes]

But is there a way to do this multiplication using metaprogramming? I´ve 
been trying to do it, however, I always end up having to use some 
execution-time based parameter and of course then the template stuff does 
not work.
To represent the matrix rows, I use a STL vector, which is dynamic so I can 
discard all zero-values and have a matrix with variable row size.

Thanks in advance,
Carol.
