So I went and installed Math::Matrix, which does matrices ok, except I could not find a way to do an inverse (which I really really need) even though it said as the header for the documentation it could do inversion, but there was no routine for it.

So then I decided to try the PDL because it said that it could do inversion and actually had a command called "inv" listed. I got PDL::Matrix and PDL::MatrixOps modules loaded up,

root@admin PDL-2.4.2# perl -MPDL::Matrix -e shell
root@admin PDL-2.4.2# perl -MPDL::MatrixOps -e shell
root@admin PDL-2.4.2#

but when I tried to run a simple program to confirm it was working I got this error:

Can't locate object method "xchg" via package "PDL::Matrix" at /usr/lib/perl5/site_perl/5.8.3/i386-linux-thread-multi/PDL/Matrix.pm line 137.

I am now lost. I do not know what this means except that there might be some module that I need loaded that I forgot to load. Any ideas?
