I'm also highly interested in sparse matrix support since I work in
the area of finite elements. There are several sparse packages in
Fortran but recently I met one that is in C++: meschach from David
E. Steward & Zbigniew Leyk from Australia. I don't know about the
legal part. This is the copyright,

BTW, are there any projects around of writing an interface to the Mesa
graphics library? Right now, I wrote a small program to see surfaces
and plot streamlines (fluid mechanics), but I simply write from octave
a data file, and after I read this from the small C program. I wonder
if someone has made somegthing better. Mesa is GPL.
Cheers,
Mario
