1. Matheval.e
I just sent matheval.e to Rob to put up on the contribution page. With some
interest lately regarding doing math in euphoria (NOT a f.p. post!), I
thought this was a good time to send it out.
I wrote it because the expression evaluators that have been written were not
very advanced mathematically speaking (not that my little effort doesn't
have a long way to go!), especially in the treatment of variables. In
matheval, any value can be stored in a variable, including expressions of
arbitrary size/complexity.
It supports some VERY rudimentary calculus routines, algebraic solving
methods, and matrix arithmetic (inversion routines use Art Adamson's
matrix.e, found in the archives).
Included are a coulpe of demos. One just parses and evaluates some
expressions and spits out the results. The other uses win32lib (not
included) to do regression.
In fact, I plan to expand it into a scripting language, to enable fairly
complex algorithms to be coded--OK, OK, it won't be the fastest thing
around, but it's very flexible.
