Kig is a program for exploring geometric constructions. It is meant as a better replacement for such free programs as KGeo, KSeg and Dr. Geo and commercial programs like Cabri. Kig is meant as a useful and powerful utility for high school students and teachers.

This is an interactive generative art application to evolve images/textures/patterns/animations through an iterative process of random mutation and user-selection driven evolution. This process is also often referred to as "evolutionary art" or ... [More] "genetic art". If you like lava lamps, and still think the Mandelbrot set is cool, this could be the software for you. [Less]

JEuclid is a complete MathML rendering solution, consisting of: * A MathViewer application * Command line converters from MathML to other formats * An ant task for automated conversion * Display components for AWT and Swing * A component for Apache Cocoon * A plug-in for Apache FOP

KAlgebra is a mathematical calculator based content markup MathML language. Nowadays it is capable to make simple MathML operations (arithmetic and logical) and represent 2D and 3D graphs. It is actually not necessary to know MathML to use KAlgebra.

KTurtle is an educational programming environment. KTurtle aims to make programming as easy and touchable as possible, and therefore can be used to teach kids the basics of math, geometry and... programming. The programming language used in KTurtle ... [More] is loosly based on Logo. KTurtle allows, just like some implementations of Logo, to translate the programming language (the commands, the documentation and the error messages) to native language of the programmer. Translating the programming language to the native language of the programmer is one of the many ways KTurtle tries to make learning to programming more simple. Other features to help to achieve this goal are: intuitive syntax highlighting, simple error messages, integrated canvas to make drawings on, integrated help function, ... [Less]

An implementation of linear algebra numerical structures and methods for the CLR. NPack is unique in that it uses generics for matrix element definitions, and a set of matrix operations via an interface, allowing a CLR-based operations engine as well ... [More] as the opportunity to use GPGPU-based operation engines. NPack was initially ported from Java Matrix Package (JAMA) by the US National Institute of Standards and Technology (which was a Java reinterpretation of LINPACK). [Less]

Lib2geom (2Geom in private life) is a library developed for inkscape to provide a robust computational geometry framework. It is not a rendering library, instead concentrating on high level algorithms such as computing arc length.

Set of open, reliable, math functions in classes (=collections by domains) designed to be used from any project/library, with any data-structure. In other words, all the things you usually rewrite for each project. But coded with universality in ... [More] mind. The most important package is the org.openmali.vecmath2 one, which contains an improved vecmath - similar to Sun's vecmath, but better, faster and more convenient. [Less]

Math::Symbolic is intended to offer symbolic calculation capabilities to the Perl programmer without using external (to Perl) libraries and/or applications. It's quite limited in scope. No integration of expressions, for example. However, various ... [More] extensions have been written to allow things like symbolic tree transformations using declarative syntax or compilation to Perl or C code for faster numeric evaluation. [Less]

The Universal Java Matrix Package (UJMP) is an open source Java library that provides sparse and dense matrix classes, as well as a large number of calculations for linear algebra like matrix multiplication or matrix inverse. Operations like mean ... [More] , correlation, standard deviation, replacement of missing values or mutual information are also supported. Matrices can be imported from and exported to a large number of file formats, also linking to JDBC databases is supported. The Universal Java Matrix Package supports multidimensional matrices as well as generic matrices with a specified object type and can also handle very large matrices even when they do not fit into memory. [Less]

Uncommons Maths is a Java library consisting of a comprehensive random numbers package and other useful mathematical utility classes.

IT: Questo progetto è composto da una classe php che traduce, in modo naive, espressioni matematiche in istruzioni php. EN: This project is composed by a php class able to quickly translate mathematical expressions in php instructions.

Console scientific calculator which support know : cos,atan,ln,exp,derive,prime test,... It works on Windows and Linux.

Gravit is a gravity simulator which runs under Linux, Windows and Mac OS X. It's released under the GNU General Public License which makes it free. It uses Newtonian physics using the Barnes-Hut N-body algorithm. Although the main goal of Gravit is ... [More] to be as accurate as possible, it also creates beautiful looking gravity patterns. It records the history of each particle so it can animate and display a path of its travels. At any stage you can rotate your view in 3D and zoom in and out. Gravit uses OpenGL with Lua, SDL, SDL_ttf and SDL_image. [Less]

XMDS is a code generator that integrates equations. You write them down in human readable form in a XML file, and it goes away and writes and compiles a C++ program that integrates those equations as fast as it can possibly be done in your architecture.

Compass and Ruler (C.a.R.) is a dynamic geometry software developed by Rene Grothmann since 1989.

mjbWorld is a standards based 3D editor, which can graphically edit and allow users to see and interact with X3D (VRML) and other 3D formats. It is also intended to provide a platform which can be used to experiment with physics, animation, etc. Versions for Java, C++ and C# are included.

KBruch is a small program to practice calculating with fractions. 4 different exercises are offered: * Exercise Fraction Task - in this exercise you have to solve a given fraction task. You have to enter numerator and denominator. This is the main ... [More] exercise. The difficulty of this task can be influenced by the user. The user can decide if he wants to solve tasks with addition/substraction and/or multiplication/division. Also he can set the number of fractions and the maximum size of the main denominator. * Exercise Comparison - in this exercise you have to compare the size of 2 given fractions. * Exercise Conversion - in this exercise you have to convert a given number into a fraction. * Exercise Factorization - in this exercise you have to factorize a given number into its prime factors. [Less]

KPercentage is a small math application that will help pupils to improve their skills in calculating percentages. There is a special training section for the three basic tasks. Finally the pupil can select a random mode, in which all three tasks are mixed randomly.
