The JACAL Symbolic Math System

Current Version	Released	Terms
1c3	2013-05-10	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:

Supports GNU configure.
Makefile: Reorganized per http://www.gnu.org/prep/standards/.
English.scm (tps:2d): Put space between brackets and matrix contents in order to distinguish between bunch and matrix.
jacal.texi: Added documentation for missing commands.
(Guile 1.8.6 and 1.8.7): Supported.

From Vytautas Jancauskas:

Interpolation commands: interp.lagrange, interp.newton, interp.neville, interp (Hermite).

From Sarah V. Jaffer:

All built-in commands now check for correct number of arguments.
