Greetings everyone,

I've put together a small set (a 4k page) of math FOCAL programs, based on the Advantage ROM capabilities and as examples of many of the SANDBOX ROM functions.

Its contents covers the usual suspects, or rather extensions to them:

- enhanced matrix editors and routines,

- special functions (Bessel, Gamma, Beta, Dseta)

- polynomial roots (any degree)

- polynomial curve fitting (Valentin's finest)

- polynomial interpolation (as posted by Ulrich Deiters)

- *simple* complex math (SIN, COS, TAN, LN)

- and a few others

It also has a set of MCODE functions to create and manipulate buffers (as written by David Yerka), sort of an extra bonus if you want.

Notice that I'm not a mathematician, but an EE. Most of the programs were originally written during my college years many moons ago. Some are powerful but very slow - which BTW can be obviated using V41 in turbo speed.

I'll be glad to share it with anyone interested. Just let me know, and if the interest is there I could see to post it on the web.

Best,

ÁM.
