I think this one of those few instances where Perl is the wrong tool for the job. High speed math operations are probably best done in C++. Having said that, CGI is best done in Perl :-)

Anyway, a quick search on CPAN returns quite a few results, with Math::Matrix at the top of the list. I don't think it's dated, just probably perfect and so not in need of changes :-D

What's the Perl structure of your matrix?
