REDUCE

Free plan

What the maker publishes

Advanced mathematics

Advanced features include matrix and non-commutative algebra, ordinary differential equations, special functions, quantifier elimination and Dirac matrix calculations. source

Core operations

It supports exact arithmetic, polynomial and rational function algebra, differentiation, integration, factorization, equation solving, simplification and graph plotting. source

Founded

1963 source

Integrations

The project describes interfaces to gnuplot for graphics and lists Run-REDUCE, GNU TeXmacs and GNU Emacs as alternative user interfaces. source

Intended users

The project describes REDUCE as intended for mathematics, science and engineering users from pre-university level onward. source

Interfaces

CSL provides a graphical interface by default, while PSL provides a command-line interface; CSL can also run in command-line mode. source

License and source

REDUCE is released free of charge under a modified BSD license, and its complete source code is available. source

Packages

REDUCE distributions include specialized packages, while separately downloadable external packages include Dimsym, GRG 3.2 and REDTEN. source

Platforms

The project distributes pre-packaged versions primarily for Windows, Apple macOS and Debian- or Red Hat-based GNU/Linux, with Linux packages limited to 64-bit processors. source

Programming and batch use

REDUCE includes a user-level programming language and supports non-interactive batch processing for large computations. source

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. source

Security and compliance

The pages reviewed describe the modified BSD license but do not state security certifications or compliance claims. source

Support

The project identifies its low-volume reduce-algebra-developers mailing list as its main support mechanism for questions, bug reports and feature requests. source

Updates

The project does not provide an automatic update facility; users update by installing REDUCE again. source

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. source
