Thanks for the reply.

Yes. I'm definitely planning to rewrite it to have a sparse matrix
data type at some point.

Right now, I'm doing it with a funtion because I want to minimize
the unknowns. I already can do DLD functions, and that means
that I know where my problems are comming from.

I'd also like to get some feedback on what's good and bad with
my initial version before I try the sparse data type.
