Re: [ublas] Using numeric::ublas::matrix<...> class with NR algorithms

Yes, I am! One of the reasons why I was looking into ublas is was the
sparse matrix and vector classes. I'm dealing with matrices that are
352x240, but most of them have zero elements, and it just seemed to be
a big waste of memory to have dense matrices.

I'm assuming  your answer is yes, so I'm going to plunge ahead and see
what happens :-)
Thanks for the help
