[vtkusers] Lineair systeme resolution

[heike hufnagel]

Hello,

I am not an expert either on this, but I can recommend
to look for methods adapted to your problem, that is,
your matrix characteristics (e.g. in the book of G.
Golub "Matrix Computation").
Here the link for gsl:

http://www.gnu.org/software/gsl/
