Its not supercomputer level, but I have a sparse matrix solver in my contrib. I use it along with haskell as simple replacement for octave. It is mostly a collection of scripts right I am hoping to consolidate it later as a single package. I also cannot give you a alot of example mainly because it will translate to an actual project I did for my day job although those were done on mathcad I did notice that for some plotting needs simply piping it plot command is adequate instead of bloating my tools with plot routines. fernan -- http://www.fernski.com
