*Yet Another Computer Algebra System*

**Branch:** pkgsrc-2009Q2,

**Version: **1.0.63nb1,

**Package name:** yacas-1.0.63nb1,

**Maintainer: **pkgsrc-usersYacas (Yet Another Computer Algebra System) is a small and highly flexible

computer algebra language. The syntax uses a infix-operator grammar

parser. The distribution contains a small library of mathematical functions,

but its real strength is in the language in which you can easily write your

own symbolic manipulation algorithms. It supports arbitrary precision

arithmetic.

The current version is 1.0.28 (the first release was 1.0.0). The language is

very much in a finished state. Any code written for it should be usable in

future versions. Also, the language should prove very easy to learn.

Yacas is written in very clean c++ code, and is very portable . It can compile

stand-alone, and is easily embeddable. Yacas contains a native arbitrary

precision arithmetic module, but can also be used with GMP.

Things implemented include: arbitrary precision, rational numeric, vector,

complex, and matrix computations (including inverses and determinants and

solving matrix equations), derivatives, solving, Taylor series, numerical

solving (Newtons method), and a lot more non-mathematical algorithms. The

language natively supports variables and user-defined functions. There is

basic support for polynomials.
