Generic simple and efficient Fast Fourier Transforms (FFT) implementation using policy-based design and template metaprogramming in C++

A user-friendly GTK+ GUI for SymPy

GNNS - GNNS Neural Network Simulator, is both a set of libraries and an interface for creating and learning neural networks. It is aimed to support as many network typs and learning algorithms as possible. GNNS is meant to support different platforms.

Mathematical library for GNU Pascal

Galapago is a Java application that uses LOGO-like scripting to render mathematical-biological structures.

Gato (Graph Animation Toolbox): Animate graph algorithms for example for computing shortest paths, minimal spanning trees, maximum flows or maximal cardinality or weight matchings. Create your own animations using the Animated Data Structures (ADS).

Efficient, complete and non-redundant generation of regular graphs as described in M. Meringer: Fast Generation of Regular Graphs and Construction of Cages. Journal of Graph Theory 30, 137-146, 1999.

The General Hidden Markov Model Library (GHMM) is a C library with additional Python bindings implementing a wide range of types of Hidden Markov Models and algorithms: discrete, continous emissions, basic training, HMM clustering, HMM mixtures.

Geodes is a mac application designed to do geometry and math like you can do in front of a sheet of paper. It both includes simple figures drawing (lines, circles) and high level analytic geometry.

Library intended for construction, evaluation, manipulation and visualization of geometric objects, especially for parametric and implicit defined surfaces

Gurux Data Refinery collects data directly from physical device or data stream, processes it, and presents the results, with easy-to-use components. All data is collected and saved with a timestamp, and the data is always time-bound. To release durin

HLM is a proof assistant for everyday mathematics, which is currently being developed. It aims for a user experience as close as possible to regular mathematical practice, and proofs which are understandable by humans with little extra effort.

This utility can generate very large (and high quality) probable prime numbers as well as test for primality.

A Python program for exploring the Hénon attractor. For an explanation of what the Hénon attractor is please see Wikipedia (http://en.wikipedia.org/wiki/H%C3%A9non_map). With this program you can draw the Hénon attractor and interact with it in various ways. You can zoom in by selecting an area, vary the Henon parameters manually and even make animations with them. The functionality is demonstrated in a Youtube video. There is a help function included that explains in more detail how to use the program.

Realtime bigdata tool at the bit level based on immutable AVL forest which can be run in memory or, in future versions, as a merkle forest like a blockchain. Main object is a sparse bit string (Bits) that efficiently scales up to 2^63 bits normally compressed as forest has duplicated substrings. Bits objects support reading bit, byte, short, int, or long (Java primitives) at any bit index in 64 bit range. Example: instead of building a class to hold a header and then data, represent all of that as Bits, subranges of them, and ints for sizes of its parts. Expansion ability for other kinds of compression, since Bits is a Java interface. Main functions on bits are substring, concat, number of 0 or 1 bits, and number of bits (size). All those operations can be done millions of times per second regardless of size because the AVL forest reuses existing branches recursively. Theres a scalar (originally for copy/pasting subranges of sounds) and a bit Java package. Sparse n dimensional matrix.

This simple tool allows you to quickly covert between Imperial and Metric units of measurement. Currently it supports the following units of measurement: Millimeters(mm) Centimeters(cm) Meters(m) Kilometers(km) Inches Feet Yards Miles More units may be added in the future.

IMathAS is a web-based math assessment and homework system. It is a course/learning management system (CMS/LMS/VLE) and testing system featuring algorithmic questions, similar to WebWork, Webassign, and publisher systems like iLrn, MathXL, etc.

The library provides an implementation of intervals for Ada. It includes arithmetic and relational operations. The library supports intervals with integer and floating-point bounds. Dimensioned intervals are also supported

“JEDI Math” is a free mathematical library developed under the MPL for Delphi, Kylix, FPC and Lazarus. The library provides routines for matrices/vectors, regression, geometry, physics, equation rendering and raytracing among others.

JOrrery simulates the motion of planets moving under gravity. It comes with a number of initial "scenarios" you can run, such as "The solar system", "Earth & Moon" etc. You can also add more planets during a simulation.

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.

A full math Java class library containing complex functions and algorithms such as cubic-spline interpolation, least squares, matrix computations. Eventually to make a web based interface to the library using JSP.

A thoughtfully designed Java library for dealing with Matrices ( Matrix Theory ). Simple, Intuitive and Flexible. The library revolves around a Matrix interface. Operations are thoughtfully distributed. Not guilty of exposing all-in-one Matrix class.

The goal of this fractal renderer is to enable intricate images to be created with maximum control over the results. To this end, it supports multiple layers, many fractal types (including user – defined equations) and different ways of rendering.
