Descartes should be able to handle what you want, but perhaps not terribly conveniently. It does a nice job interpreting formulas, and is able to handle a variety of functions, even differentiating equations if you want. It's also very inexpensive. On the other hand, don't expect a professional quality tool. It offers little to no support for labels, titles, etc.; it does only screen dump printouts; it makes rather elementary Amiga programming errors (hardcoded "df0:", and it busy-waits incessantly); and it has no macros, command language, or anything of that sort. For $35, which is what I paid for it at Software Etc., you could do worse. But if you are a programmer type, you might write something that fits your needs better using the plplot routines posted recently. -- Eric Kennedy ejkst@cis.unix.pitt.edu
