This is
not the answer you are looking for, but an alternative
module for dealing with matrices is the Perl Data Language.
The module PDL::Slatec has a function called
matinv
, which is gives the inverse of a square matrix like so,
($inv) = matinv($mat) (pretty much stolen from
the docs)
You will probably lose a little time installing and learning
how to form the matrix, but if you are regularly involved in
Numerical Funny Business, it might be worth it in the long
run. The web page is
http://pdl.perl.org/ which will explain the module and
lead you to a low traffic mailing list with lotsa helpful
people.
