Core operations

It supports exact arithmetic, polynomial and rational function algebra, differentiation, integration, factorization, equation solving, simplification and graph plotting.reduce-algebra.sourceforge.io · read 11 Oct 2026

Integrations

The project describes interfaces to gnuplot for graphics and lists Run-REDUCE, GNU TeXmacs and GNU Emacs as alternative user interfaces.reduce-algebra.sourceforge.io · read 11 Oct 2026

Intended users

The project describes REDUCE as intended for mathematics, science and engineering users from pre-university level onward.reduce-algebra.sourceforge.io · read 11 Oct 2026

Interfaces

CSL provides a graphical interface by default, while PSL provides a command-line interface; CSL can also run in command-line mode.reduce-algebra.sourceforge.io · read 11 Oct 2026

License and source

REDUCE is released free of charge under a modified BSD license, and its complete source code is available.reduce-algebra.sourceforge.io · read 11 Oct 2026

Packages

REDUCE distributions include specialized packages, while separately downloadable external packages include Dimsym, GRG 3.2 and REDTEN.reduce-algebra.sourceforge.io · read 11 Oct 2026

Programming and batch use

REDUCE includes a user-level programming language and supports non-interactive batch processing for large computations.reduce-algebra.sourceforge.io · read 11 Oct 2026

Purpose

REDUCE is a portable general-purpose computer algebra system for scalar, vector and matrix algebra, with arbitrary-precision numerical approximation and graphics through gnuplot.reduce-algebra.sourceforge.io · read 11 Oct 2026

Security and compliance

The pages reviewed describe the modified BSD license but do not state security certifications or compliance claims.reduce-algebra.sourceforge.io · read 11 Oct 2026

Support

The project identifies its low-volume reduce-algebra-developers mailing list as its main support mechanism for questions, bug reports and feature requests.reduce-algebra.sourceforge.io · read 11 Oct 2026

Updates

The project does not provide an automatic update facility; users update by installing REDUCE again.reduce-algebra.sourceforge.io · read 11 Oct 2026

Usage limitation

The support page says REDUCE is better at concrete problems, such as matrices with specified elements, than abstract problems such as vector spaces of arbitrary dimension.reduce-algebra.sourceforge.io · read 11 Oct 2026
