Open Source Lisp Scientific/Engineering Software

Maxima is a computer algebra system comparable to commercial systems like Mathematica and Maple. It emphasizes symbolic mathematical computation: algebra, trigonometry, calculus, and much more. For example, Maxima solves x^2-r*x-s^2-r*s=0, giving the symbolic results [x=r+s, x=-s]. It can also calculate with exact integers and fractions, native floating-point, and high-precision big floats. Maxima has user-friendly front-ends, an online manual, plotting commands, and numerical libraries. It features its own programming language, and many users have contributed useful packages in various areas over the decades. It is GPL-licensed and largely written in Common Lisp. Executables can be downloaded for Windows, Mac, Linux, and Android; source code is also available. An active community maintains and extends the system. Website: https://maxima.sourceforge.io Additional add-on packages for Maxima can be found at: https://github.com/maxima-project-on-github/maxima-packages

wxMaxima is a cross-platform graphical front-end for the computer algebra system Maxima based on wxWidgets. It provides nice display of mathematical output and easy access to Maxima functions through menus and dialogs. This project has moved to github and can be reached at http://wxmaxima-developers.github.io/wxmaxima/

CLISP is a portable ANSI Common Lisp implementation and development environment by Bruno Haible. Interpreter, compiler, debugger, CLOS, MOP, FFI, Unicode, sockets, CLX. UI in English, German, French, Spanish, Dutch, Russian, and Danish.

REDUCE is an interactive system for general algebraic computations of interest to mathematicians, scientists and engineers. It can be used interactively for simple calculations but also provides a flexible and expressive user programming language. The development of the REDUCE computer algebra system was started in the 1960s by Anthony C. Hearn. Since then, many scientists from all over the world have contributed to its development. REDUCE has a long and distinguished place in the history of computer algebra systems. Other systems that address some of the same issues but sometimes with rather different emphasis are Axiom, Derive, Macsyma (Maxima), Maple, Mathematica and MuPAD. REDUCE primarily runs on either Portable Standard Lisp (PSL) or Codemist Standard Lisp (CSL), both of which are included in the SourceForge distribution. By modern standards, REDUCE is a surprisingly small and compact application, which runs well on all major operating systems.

N.B. SuperCollider is now hosted at GitHub, and the most recent versions can be downloaded from there. http://supercollider.github.io A real time audio synthesis engine, and an object-oriented programming language specialised for music.

ST je stavařská nadstavba pro AutoCAD a IntelliCAD napsaná v AutoLISPu. První řádky byly napsány někdy v říjnu 1999. Z počátku měl celý projekt sloužit jen k připomenutí a zdokonalení se v AutoLISPu. Časem ale vzniklo dost funkcí, které pokud by se poskládaly dohromady, byl by z toho celkem užitečný celek. První použitelné verze byly k dispozici v létě 2000. Spolehlivě fungovaly ale jen pod A2000. Skutečně spolehlivá verze byla až verze 1.40, o té se i přes všechny nedostatky dalo říci, že dělala, co měla. Celý program je napsán tak, aby sloužil jen jako pomocný nástroj, tj. aby příliš nediktoval styl práce a neomezoval svými nedostatky další práci. Doufám, že se to aspoň z části povedlo. Program obsahuje funkce na kreslení, kótování, popisování a pomocné funkce.
