The JACAL Symbolic Math System

Current Version	Released	Terms
1c8	2020-03-02	GPL 3.0

JACAL is an interactive symbolic mathematics program. JACAL can manipulate and simplify equations, scalars, vectors, and matrices of single and multiple valued algebraic expressions containing numbers, variables, radicals, and algebraic differential, and holonomic functions. JACAL is a GNU package.

New:

Jacal now does integration of rational functions whose integrals are rational functions optionally containing a radical involving the integration variable. The integration algorithm is documented in http://people.csail.mit.edu/jaffer/ratint.pdf
