JUNG provides a common and extendible language for the modeling, analysis, and visualization of data that can be represented as a graph or network.
New version now available on GitHub: https://github.com/jrtom/jung/releases/tag/jung-2.1
GeoGebra is free and multi-platform dynamic mathematics software for learning and teaching geometry, algebra, statistics, and calculus. Download the free software at http://www.geogebra.org. Find the source code at http://www.geogebra.org/trac
Java-based number generator package. Includes several strategies, apart from the usual random: constant, serial, function, composite.
Besides, generators can be wrapped in different filters to obtain modified data series.
Superficially, Dominoes on Acid is a solitaire variant of Dominoes with weird colorful tiles. But on a deeper level it is a GUI for natural deduction. Every completed domino is equivalent to a proof of a tautology in classical propositional logic.
Maximally flat (maxflat) digital filter design in Java, with arbitrary numbers of poles and zeros. "Maximally flat" means that the magnitude frequency response has the maximum number of vanishing derivatives at 0 and pi.
This is a simple program that will factor a quadratic trinomial using both "guess-and-check" and the quadratic formula. You input a, b, and c, where ax^2+bx+c=0; you will get a result in the form of (ax+b)(cx+d)=0 and x=a or x=b.
CaRMetal is a dynamic geometry software : it provides to the teachers and pupils of primary , secondary school and university an environment which allows to investigate, in a interactive way, the geometrical properties of figures.
This is a set of business math tools. The intended users are American business students. Some features include interest calculations, mortgage payment calculations, markup and markdown calculations and others.
JMulTi is an interactive software designed for univariate and multivariate time series analysis. It has a Java graphical user interface that uses an external engine for statistical computations. It uses the framework JStatCom.
Mad Math is a Math API for Java that is aimed at adding needed math functions and formulas that are not in the regular Java Math API, such as fibonacci sequence, is prime, area formulas, greatest common factor, least common multiple etc.
A fully customizable, extensible, scalable computational engine pluggable with various statistical and mathematical engines (R, Matlab, Octave, scilab...) The main focus and datatype considered is timeseries: the project contains also a portable and effi
JBendge - Bayesian Estimation of Nonlinear Dynamic General Equilibrium Models. The project provides a toolkit together with a graphical user interface for the specification, solution, estimation and simulation of models.
We produced a software for scientists and managers working with marinas, and small harbor. Our software is able to predict the distribution of portuality and vulnerability risk.
Geoplan-Geospace is a 2D and 3D interactive geometry software to create and manipulate interactive figures for eLearning. It features euclidean geometry objects (lines, circles), numerical functions, numerical sequences, geometrical transformations.
A project to help students calculate symbolic derivatives and integrals. Plus, a Java expression tree library for developers who may need to do such things in their programs.
The project has moved to github: https://github.com/generalpenguin89/calchelper
G.A.V. (Graph Algorithm Visualizer) is a tool that visualizes algorithms from graph theory. A step-by-step visualization from each different algorithm allows the user to understand the particular algorithm very easily.
The project Intergeo co-funded by the Community programme eContentplus develops an open-source library for the common file format it defines to allow developers of dynamic geometry systems to quickly integrate read support for such files.
