JACAL

JACAL is a powerful interactive mathematical software program that brings ease to the manipulation and simplification of complex equations, vectors, matrices, and scalars of single and multiple valued algebraic expressions. This program operates by handling numbers, variables, radicals, and algebraic differential, and holonomic functions seamlessly.

To use JACAL, you will need to install a Scheme implementation software. The installation procedures are straightforward, and you can follow the instructions given. If your device already has a Scheme (or Guile) implementation software installed, then the installation procedure will not require the `scm' steps. The SLIB Portable Scheme library is also necessary for JACAL to run smoothly. This library is easily accessible from the website `'.

For users on a system that runs on i386 GNU/Linux with Redhat Package Manager (rpm), download and install the relevant files using `wget' and `rpm -U' commands. Once installed, the command `jacal' will automatically establish an interactive session to begin operating JACAL.

For Unix and GNU/Linux systems, use the `wget' command to download relevant installation files and subsequently install JACAL, SCM, and SLIB using the command prompt. Type `jacal --help' for instructions on how to initiate an interactive session.

JACAL is also available for Apple devices, and users can install SCM and SLIB using `' downloads and utilities. Microsoft Windows users can download and run the software using `', `', and `'.

Compiling JACAL becomes necessary for Scheme implementations that have compilers. It is worth compiling the SLIB files, as well as the files `types.scm' and `poly.scm' that come with JACAL.

The latest release of JACAL comes with exciting new features, including support for Larceny (Scheme), improved error reporting, new logo designs, and a jacal-discuss email group, among others. Additionally, bugs found in `sexp.scm' and `builtin.scm' have been fixed.
