JRVFSim (Jarvis) is a simulator of a fluid dynamics phenomenon known as radial viscous fingering. Its main feature consists of taking jordan curves and simulating their evolution subject to various parameters. Includes a partial API for numerical methods

Java Randomness Test Suite is a gui application to run randomness tests on random stream resource (file or algorithm). Application can be run in command line. Includes general statistical tests, NIST and DIEHARD tests.

Raytracing rendering engine written in Java. Plug it into a modeling environment, or programmatically create a scene. Uses Constructive Solid Geometries (CSG), bounding boxes, and fully extensible design (at least eventually).

JREC is a framework for building finite state automatons from regular expressions based on a general grammar.

A java command-line application where the main goal is to solve any simplex problem. It's a team-work school project. It can be usefull for other students who needs to understand the simplex algorithm.

JTSA is an educational time series analysis tool for simple calculations and forecasts using the additional or multiplicative seasonal decomposition method.

JavaANPR is an automatic number plate recognition software, which implements algorithmic and mathematical principles from field of artificial intelligence, machine vision and neural networks.

A graph library, developed in Java.

Logo command and construct library for Java. Intended as a tool for teaching novice programmers the Java language and object orientation.

Javafastcomplex is a fast complex number package for Java. Most existing complex number packages implement only immutable complex numbers, which is easy to understand given that immutable objects lead to more understandable code. Mutable complex numbers would avoid garbage-collection penalty and therefore be faster in calculations. Javafastcomplex implements both mutable and immutable complex numbers, and has a common interface for both, allowing users to write functions that can take either a mutable or an immutable complex number as an argument. Mutable complex numbers can then be used in the most performance-critical parts of the code with immutable complex numbers being used elsewhere. Performance improvement of mutable complex numbers is 10x in the best-case scenario and about 2x in real life complex number code. The package is released under the liberal MIT license.

Evaluate an arithmetic expression is as simple as: Double result = new DoubleEvaluator().evaluate("(e^3-1)*sin(pi/4)*ln(pi^2)"). But Javaluator provides you with much more ... Key features: - Functions support, including variable argument count. - Constants support: e, pi, etc ... - Variables support: Example sin(x) for x = pi/4. - Highly configurable: Reduce the built-in operator or function sets, define your own brackets. - Extensible: Define your own grammar, or extends the existing one. - Localizable: Define localized names for functions or constants. - Syntax check - Small footprint: 26kB, no additionnal library required. - Fully documented Please visit the project site to learn more : http://javaluator.fathzer.com If you use Javaluator in your product, we will be happy to add a link to your product in the Javaluator web site. Send an email to javaluator@fathzer.com. If you think Javaluator is valuable, vote up below.

A tool for visualizing regular polytopes in stereographic projection. Capabilities include: a large database of Coxeter polytopes, 6-axis motion control, animation, fly-though, stereo viewing, high-res capture, depth-blur, and many style options.

This project provides an interface to Java expression evaluator software. It does not itself provide expression capabilities but instead provides a common interface.

An implementation of the Joint Generation Algorithm of Fredman and Khachiyan for the computation of a dual pair of monotone boolean formulas in DNF (hypergraph transversals, extreme rays of polyhedral cones...). User-replaceable oracle.

An online judge system to judge the ACM-ICPC programming contests.

KAlgebra is a MathML-based graphic calculator, thought to bring to the user its power by solving expressions written in MathML or calculating converted common equations to MathML. This project now belongs to KDE Edu. http://edu.kde.org

With this program you can do Geometry on a computer just like you would do it on a blackboard in a classroom. However, the computer allows you to go beyond that, since Euklid are designed to do interactive Geometry.

KGameOfLife is an application that simulates the classical Game of Life invented by John Conway. It consists of a collection of cells on a board which, based on a few mathematical rules, can live, die or multiply.

KHorn is a universal easy to use CAS (Computer Algebra System). It will be usable for Physics, Chemistry, Mathematics and other natural sciences. KHorn is based on the GMP library.

KL1p is a portable C++ framework for handling sparse recovery of inverse problems of underdetermined linear systems, like in compressed sensing technique.

KPNClac is a polish notation calculator intended to inspired by the HP48 Series calculators. It handles complex numbers and will someday handle matricies. The next current development version allows user programmable functions via python.

KSciPlot is a function plotter for the KDE environment. It supports embedding in KOffice applications, deriving functions, polar plots, etc.

KStochastic gives the user the ability to create pictures of stochastic processes based on arbitrary probability distributions. Those pictures can then be used for illustration purposes in various publications treating random phenomena.
