NOTE: Yacas and yagy development has moved to github. The new repositories are located at https://github.com/grzegorzmazur/yacas and https://github.com/grzegorzmazur/yagy . The mailing list has been moved over to https://groups.google.com/forum/#!forum/yacas . The downloads section at sourceforge will be kept up to date for the foreseable future. Yacas is an easy to use, general purpose computer algebra system. It uses its own programming language designed for symbolic as well as arbitrary-precision numerical computations. The system comes with a library of scripts and extensive documentation. Yagy (http://sourceforge.net/p/yagy) provides full yacas experience wrapped in a simple and intuitive graphical interface.

Lush is a Lisp dialect with extensions for object-oriented and array-oriented programming. Lush is intended for prototyping numerically intensive applications and is designed for easy integration of existing C/C++/Fortran codes.

Community Z Tools Project (CZT): Tools for editing, typechecking and animating Z specifications and related notations. Includes a Java framework for building formal methods tools. NOTE: development of CZT has now moved to GitHub: https://github.com/community-z-users/czt

Yorick is an interpreted programming language for scientific simulations or calculations, postprocessing or steering large simulation codes, interactive scientific graphics, and reading, writing, or translating large files of numbers.

GDL - GNU Data Language, a free IDL (Interactive Data Language, see http://ittvis.com/idl/) compatible incremental compiler.

Brandy is an interpreter for BBC Basic (or Basic V) that runs under a variety of operating systems. Basic V is the version of Basic supplied with desktop computers running RISC OS. These were originally made by Acorn Computers.

Algae is a programming language for numerical analysis. We wrote it because we needed a fast and versatile tool, capable of handling large systems. Algae has been applied to interesting problems in aerospace and related fields for more than a decade.

FrAid(FRactal AID) is an interface to Java, allowing it to proc. math. data(functions/equations). A compl. standalone system utilizing the FrAid prog. lang. is available(no need to be Java programmer to use it!). Use instead of Matlab. High res. graphics

Franklin Math is an open source Java symbolic computer algebra system (CAS), with similarities to commercial math packages such as MATLAB or Mathematica. It allows numeric and symbolic calculations, with built-in functions including plotting commands.

MScheme is a Scheme interpreter implemented in Java. The project goals are to fully comply with the "Revised^5 Report on Scheme" and a clean and modular design.

RLaB is a high level programming language targeted at engineering applications. Rlab is _not_ a clone of languages like Matlab. Though, it can be called "MATLAB-like" since the programming language possesses similar operators and concepts.

Xconq is an engine for turn-based strategy games. Variety of game genres run under Xconq: historical, sci-fi, fantasy, and modern. AIs. Network games. Multiple UIs and platforms. Easy-to-learn game design language. Large games library available

A Python interface to the GSL library. The wrapper covers nearly everything GSL provides.

AUTOMGEN runtime is an open source royalty free runtime for open PLCs. By using this runtime, any target systems can become compatible with the AUTOMGEN automation workshop: IEC1131 languages (ladder, SFC, etc.), 2D and 3D scada, WEB SCADA, etc.

Java library for parsing and evaluating math expressions. Javadoc is available at http://bracer.sourceforge.net/javadoc/ P.S. This library depends on Apache Commons Math, so don't forget to include commons-math-2.2.jar to your project.

Symbolic math Java applet. Features: big number arithmetic; symbolic and numeric evaluation; programming language constructs;plot functions

LCI is an interpreter for the lambda calculus. It supports many advances features like integers, recursion, user defined operators and multiple evaluation strategies.

YABI93 is an Interpreter for the esoteric programming language Befunge, version "Befunge93". It is written in Java 1.5 and uses Swing for its graphical interface. YABI supports a multilanguage GUI.

Spar is a math-oriented scripting language. It is simple, clean, and extensible.

Script language independent library for calling functions out of script files with other PLs like C/C++. This should be possible, using only some few functions as interface.

The Basil project's mission is to build a parsing and modeling environment where one is able to work with, code in, integrate, and design a wide variety of computer languages.
