I was hoping for rational solutions. If I were a true jedi master I'd write my own solver, which might be the right thing to do. All I know so far is gauss' method. Probably I'd learn something implementing the back substitution. hmm....

The Hugs interpreter has a few nice Haskell demos, including a simple gauss elimination http://darcs.haskell.org/hugs98/demos/Matrix.hs Of course, this is unsuitable for serious floating point calculations. Regards, apfelmus
