That's too bad, many big numerical computations are highly parallelizable which
seems to be the big sell of erlang. Are there reasons these problems are not
solved with erlang? I wrote my own quick and dirty rational module to do what I
need for now.

This does indeed have vector and matrix operations, but not for the general
case. (I was pleasantly surprised however by how easy it was to understand their
code. Perhaps that's a tribute to erlang.) I'd want to do much larger matrix
operations. Any thoughts on how to represent a matrix with erlang? (dense or
sparse) Would a list of lists be good enough or would there be a better way?

Sigh, perhaps it's time for a change. I've had this email for a very long time.
I play the horn. Well, played until I got these blasted braces. They make it
quite a bit more difficult.
