Projects

GNU Octave

Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments. It may also be used as a batch-oriented language.

Maxima -- GPL CAS based on DOE-MACSYMA

Maxima is a system for the manipulation of symbolic and numerical expressions, including differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations, systems of linear equations, polynomials, and sets, lists, vectors, matrices, and tensors. Maxima yields high ... [More] precision numeric results by using exact fractions, arbitrary precision integers, and variable precision floating point numbers. Maxima can plot functions and data in two and three dimensions. The Maxima source code can be compiled on many systems, including Windows, Linux, and MacOS X. The source code for all systems and precompiled binaries for Windows and Linux are available at the SourceForge file manager. [Less]

QtOctave

QtOctave is a front-end for Octave. Octave is a high-level language for numerical computations, like Matlab.

DUNE-project

DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations (PDEs) with grid-based methods. It supports the easy implementation of methods like Finite Elements (FE), Finite Volumes (FV), and also Finite Differences (FD).

Kig

claimed by KDE

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.

KmPlot

claimed by KDE

KmPlot is a mathematical function plotter. It has a powerful parser built in. You can plot different functions simultaneously and combine their function terms to build new functions. KmPlot supports functions with parameters and functions in polar coordinates. Several grid modes are possible. Plots ... [More] may be printed with high precision in correct scale. Features * powerful mathematical parser * precise metric printing * different plot types (functions, parametric, polar) * highly configurable visual settings (plot line, axes, grid) * export to bitmap format (BMP and PNG) and scalable vector graphics (SVG) * save/load complete session in readable xml format * trace mode: cross hair following plot, coordinates shown in the status bar support zooming and more.

JEuclid

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

LAPACK

LAPACK provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems. The associated matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are also provided, as are ... [More] related computations such as reordering of the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, but not general sparse matrices. In all areas, similar functionality is provided for real and complex matrices, in both single and double precision. Note: Ohloh's statistics are not accurate. LAPACK has dozens of major contributors, but most do not use any form of source control. Contributions are merged by only a few people, and then only in bursts. [Less]

lib2geom

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.

Gravit

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 to be as accurate as possible, it also creates ... [More] 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]
