Solve equations ...

Hi,

I would like to solve a system of equations for
example a system 6x6 with perl. But I really don't
know how to do it. First is it possible and then if
yes how?

Thank you,

Romain

I wrote a module for that: Math::Systems. It's slow and bad, and really, just
a front end to Cramer's law (which you might want to look into) :-) Also,
this, among other mathematical topics, is discussed in "Mastering Algorithms with
Perl"

Solving simulataneous linear equations can be
(and is best done) with matrices. The coefficients
of the variables become the matrix elements.

So look at the various Matrix modules on cpan and
try to get one that uses c and xs for speed.

The PDL module, is well respected, and can do matrices.
