You might be interested by my GAP package "polyhedral" available from http://www.liga.ens.fr/~dutour/Polyhedral/index.html
which would contain all you need. The problem is that there is no manual, there is a lot of external programs to compile. But overall, it might fit your needs and much more. This is basically the way: write files, call external program, use perl script to convert to GAP readable and load the result back. >> BTW, I am interested in any kind of implementation of fast exact >> rational simplex method. cdd and lrs are such. But this all depends on what you really need. _______________________________________________ Forum mailing list [email protected] http://mail.gap-system.org/mailman/listinfo/forum
