I have a rather large matrix (200 columns by several hundred to thousands of rows) that I would like to be able to take slices of (select columns, rows) and then operate on the slices (like plotting, etc.). In the spirit of perl's many ways to do this, can folks point me to useful modules (one is Math::Matrix that looks rather dated) that might allow me to do this fast (this will be used in a CGI environment)?

Thanks.
