Hallo ^* ! I am looking for matrix routines written in C or Fortran or Basic. For example matrix inversion routine(Gauss,Jacobi,..) Jan

I have a number of routines for linear equations, including Gaussian
elimination, singular value decomposition, etc. from a variety of
sources, in several languages, some in real and complex arithmetic.
You'd have to get in touch with me for what you want. I don't have
a full EISPACK or LINPACK though - just what I've needed at various
times.
You can find assorted routines in books like 'Numerical Recepies',
as well as the ACM algorithms, and most are simple enough to just
type in a copy if you needed it. (Except for sparse matrix code, that
can get hairy.)
If anyone else has any good quality numerical analysis software online
(such as some of the things available on USENET) I'd be interested
in adding some of it to my set of tools too...

I have copies of the SSP library routines (I am converting them to FORTRAN 77 for my own amusement) and the Recipes collection is on-line - ask Mike CURIUM::PETERSON for copies and caveats. Ask for what you need specifically. Lynn Yarbrough | |||||

Here's what I use:

I'd recommend LINPACK over SSP. The developers of LINPACK were
a lot more cautious about error control than the old SSP routines.
There should be a copy of this kicking around the company somewhere.

I remember that Gilbert has a good bliss version if that is all you
want to do. (See note #126). I have EISPack and Linpack; you
might want to try NETLIB also.
Good luck.
