Numerical math is tool that demonstrates numerical math methods. It includes following areas: interpolation, numerical differentiation, numerical integration, root finding, linear systems, non-linear systems, differential equations.
Parallel Colt is a multithreaded version of Colt - a library for high performance scientific computing in Java. It contains efficient algorithms for data analysis, linear algebra, multi-dimensional arrays, Fourier transforms, statistics and histogramming
A program to calculate and create lists of possible variations (permutations) and selections (combinations) of a given set of elements. Creating the cartesian product of two sets is also possible.
The aim of this project is to produce a software that will content two modules :
- the first one will allow to conduct simulations of social behavior,
- the second one will be able to produce philosophical considerations.
The version version will be i
JFractals is a fractal generator written in Java. JFractals allows you to zoom into Julia sets and the Mandelbrot set. JFractals supports multithreaded rendering, antialiasing and multiple colouring methods.
A cross-platform, text-interpreting calculator written in the Java programming language. Runs on any computer with Java 6 or higher installed. Functions much like a Ti-84, but without the graphing utility.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
VMatrixLib is a little, handy, Java matrix library which implements a set of utility functions (such as calculus of the determinant of a matrix, calculus of the rank, inverse matrix, and many others..) that anyone who have to use matrices needs.
DragMath is a drag and drop equation editor in the form of a Java applet. Once an expression is created the user can convert it into a variety of different linear syntax for mathematics, including MathML, LaTeX, Maple, Maxima or any user defined style.
PLEASE NOTE: active code development has moved to GitHub.

A basic quadratic equation calculator written in Java with a command-line interface. Handles fractions and imaginary roots. Thanks to Doug Lea at SUNY Oswego for his work on the Fraction class.
Clados is a java package that implements a multivector in a Clifford Algebra. Algebras (over real numbers) with any signatures may be used. A calculator and associated documentation is also included to help users learn how things work.
Plexus is a Java library with specifications and implementations for generic graph data structures. Like the Java Collections Framework, vertices and edges are containers for arbitrary user-defined objects.
Maximum entropy is a powerful method for constructing statistical models of classification tasks, such as part of speech tagging in Natural Language Processing. Several example applications using maxent can be found in the OpenNLP Tools Library.
A Java library that works with Java3D to simulate and visualize, in real-time, dynamics of multiple rigid bodies that are restricted by implicit and explicit constraints (e.g., robotics); designed for efficiency, ease-of-use, and extensibility.
The general triangle solver. It computes all solutions for a triangle specified by combination of sides, angles, altitudes, medians, angle bisectors, area, radius of circumscribed and inscribed circle, sum a+b, perimeter and difference of alpha-beta.
Automata Based Programming Tool for implementing logic for J2SE, J2EE and Sybmian applications. Consists of Java FSM Framework and Eclipse Plugin parts. Plugin implements UML model editor, visual debugger, validator, compiler and interpreter for Eclipse
Fuzzy numbers and basic fuzzy arithmetics (+, -, *, /, 1/x) implementation written in Java. Should be used as a library, but it also has a GUI which demonstrates its capabilities (using SWT widgets).
Fuzzy logic add-in for OpenOffice.org Calc. InrecoLAN FuzzyMath allows to perform ordinary arithmetic operations and use ordinary mathematical and financial functions with fuzzy numbers. Have any ideas how to improve this project - you are welcome!
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
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.
