A project that allows to view random variables cdf/pdf, generate random numbers... gstatistics uses shared libraries to allow users to add new statistical laws definitions.

ivl is a full-header template C++98 math library with convenient yet powerful syntax. It extends classic C++ syntax towards mathematical notation while making use of the language's elements like classes, structs, operators and functions. Expression written using ivl are excessively optimized. In other words, ivl allows writing simpler and more expressive statements using math-like formulas while taking care of optimizing them. ivl features arrays, tuples and custom function-like objects with left-right overloading, function pipelining and function vectorization, automatic lazy evaluation, sub-arrays and other views of a single or multidimensional arrays, stl-compatible iterators, multidimensional iterators and multithreading. ivl includes a rich set of functions and operators, including operations for image processing. Seperate modules are also included. The module ivl-lina implements a linear algebra LAPACK wrapper. The module ivl-cv integrates OpenCV into ivl.

Port of Numerical Python to Jython (Java Python) to support all mathematical operations (linear algebra, matrices, DSP, wavelets, FFT, arrays...) and thus compete with commercial packages such as Matlab. It can be easily embedded in Java programs.

JStatCom is a software framework that facilitates the creation of JAVA programs for data based analysis tasks in various domains. It provides ways to call routines from specialized software packages, like Matlab, Gauss, Ox, and possibly others.

latexdiff is a Perl script, which compares two latex files and marks up significant differences between them (i.e. a diff for latex files). Various options are available for visual markup using standard latex packages such as "color.sty".

The new site is at http://psychometricon.net/libirt/ Library of functions to estimate the items and abilities from the responses of subjects to a questionnaire. The IRT models supported are the logistic model, the multivariate logistic model, the graded model and smoothing by penalization and kernel.

Some scripts for boolean calculation, including a parser. Ternary logic support. Everything is written in Posix Sh.

This program is fundamentally a short-sized version of my mathSuite program: https://sourceforge.net/projects/mathsuite/ It includes all the functionalities of MSCenv (mathSuite Calculus Environment), such as inline variables and functions (mainly thanks to ExprEval), which you can use to perform expensive complex computations and store their results into runtime variables. You can perform also every Linear Algebra Operations included in mathSuite with new optimizations.

This program manipulates representations of compact semi-simple Lie algebras. It can compute tensor products, (anti-)symmetric parts and the branching rules into maximal subalgebras.

pyGraph is tool that hopefully will help graph theory students by analizing,transforming and creating graphs Dependencies: python and pygame

pyprime is a program / library for finding prime numbers.

This package provides high-level interface utilities for MCMC models via Just Another Gibbs Sampler (JAGS), facilitating the use of parallel (or distributed) processors for multiple chains, automated control of convergence and sample length diagnostics, and evaluation of the performance of a model using drop-k validation or against simulated data. Template model specifications can be generated using a standard lme4-style formula interface to assist users less familiar with the BUGS syntax. A JAGS extension module provides additional distributions including the Pareto family of distributions, the DuMouchel prior and the half-Cauchy prior.

Simple program using Euclides algorith to simplify a fraction, by finding the greatest common divider. e.g. 2/10 becomes 1/5, but 345/456 becomes....?

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

The Great Equation Graph is a mathematical tool designed to allow representation of abstract mathematical situations and graphing of equations.

tkalc is a pocket calculator for developers and IP network operators. Arbitrary arithmetic/logical expressions can be entered very quickly. The result is then simultaneously displayed in decimal, hexadecimal, octal, binary, ASCII, IP address, and boolean.

vivienda-rbt es software libre bajo la GPL que calcula la potencia total prevista para un edificio según el reglamento electrotécnico de baja tensión. El programa pregunta al usuario el número de viviendas, ascensores, metros cuadrados de los locales, garaje, potencias, si está en planta baja, sotano, tiene o no luminarias, factor de corrección del condensador, etc, por lo que no hace ni falta saber como se aplica el reglamento al ser todo preguntas.

Tiny library written in C++/wxWidgets designed to manage mathematical objects : parser of expressions, plots, matrixes and complex numbers. Ansi and Unicode are supported. Documentation and rich samples are provided. Compiles with MSVC, BCC, GCC and Clang. Now on Git.

Expression parser of strings like sin(pi/4) is written in c++, javascript, java and php. It is also possible to create functions x0+2*sin(pi*x1) for further calculations.

Z88 a free finite elements program featuring 20 different element types for LINUX and Windows. Includes two solvers, a mesher, plot programs and a GUI with online help.

Axiom is a computer algebra system. It consists of an interpreter, a compiler and a library of algorithms. Axiom is an excellent research platform as well as a useful tool for scientific programming.

A text editor for maths. Simple algebra should be faster and more intuitive to perform on a computer than on paper and should look like maths. Write small fragments in plain text; perform simple click-and-drag algebra with the mouse; and explore more involved algebra through keyboard shortcuts. When done, save as plain text files or export to LaTeX and HTML.

transpose is a fast and efficient command-line tool that transposes (the rows become the columns, the columns become the rows) or reshapes a matrix in plain text. Inputs and outputs can be files or streams.
