geg, a GTK+ Equation Grapher is a very simple utility for parsing and plotting 2D-Functions, eg f(x) = 3 + sin(x), and much more complicated functions. It was written with GTK+ and provides a neat, configurable user interface.

The GLPK package is a set of routines written in ANSI C and organized in the form of a callable library. This package is intended for solving large-scale linear programming (LP), mixed integer linear programming (MIP) and other related problems. The GLPK package includes the following main components: * implementation of the simplex method; * implementation of the exact simplex method based on bignum (rational) arithmetic; * implementation of the primal-dual interior-point method; * implementation of the branch-and-bound method; * application program interface (API); * GNU MathProg modeling language (a subset of AMPL); * GLPSOL, a stand-alone LP/MIP solver.

The dynamic mathematics software Geonext establishes new ways of teaching and learning mathematics. It offers opportunities of visualisation that can't be realised on paper or blackboard and with traditional construction tools. Geonext enables autonomous and cooperative learning of mathematics in the classroom. It encourages an active discovering approach to mathematical thinking. Geonext can be used at school and at home for free (GPL). Therefore the software can be handed out to students without any copyright problems (GPL). Geonext can be used from elementary school up to calculus at high school and in teacher-training at university in a manifold and flexible way. -Andreas Fehlner fehlner@gmx.de

Gexpr is a shell calculator with floating point, standard C functions, relational operators, and output in base 2/8/10/16. It is a light alternative to bc(1). It can also be used to add floating point math to shell scripts.

General purpose computer algebra system released under GPLv3. French documentation by Renee De Graeve is for non-commercial use only. The package consists of: - C++ library (libgiac). It is build on C and C++ libraries: PARI, NTL (arithmetic), CoCoA (Groebner basis), GSL (numerics), GMP (big integers), MPFR (bigfloats) and provides algorithms for basic polynomial operations (product, GCD) and symbolic computations (simplifications, limits/series, symbolic integration, summation, ...). The library can be configured to accept Maple or TI syntax to ease the transition for users of these systems. - Command line interpreter (icas or giac). It can be called from texmacs. - FLTK-based GUI (xcas). It is a GUI for symbolic computation with several modules added: 2-d and 3-d graphics, dynamic 2-d and 3-d geometry (exact or numeric), spreadsheet, programming environment.

Givaro is a C++ library for arithmetic and algebraic computations. Its main features are implementations of the basic arithmetic of many mathematical entities: prime fields, extension fields, finite fields, finite rings, polynomials, algebraic numbers, arbitrary precision integers and rationals (via C++ wrappers over gmp). It also provides data structures and templated classes for the manipulation of basic algebraic objects, such as vectors, matrices (dense, sparse, and structured), univariate polynomials, and recursive multivariate polynomials.

GLgraph visualize mathematical functions. It can handle 3 unknowns (x,z,t) and can produce a 4D function with 3 space and 1 time dimension.

OpenGL Mathematics (GLM) is a header only C++ mathematics library for graphics software based on the OpenGL Shading Language (GLSL) specification. GLM provides classes and functions designed and implemented with the same naming conventions and functionalities than GLSL so that when a programmer knows GLSL, he knows GLM as well which makes it really easy to use. This project isn't limited to GLSL features. An extension system, based on the GLSL extension conventions, provides extended capabilities: matrix transformations, quaternions, half-based types, random numbers, procedural noise functions, etc... This library works perfectly with OpenGL but it also ensures interoperability with third party libraries and SDKs. It is a good candidate for software rendering (Raytracing / Rasterisation), image processing, physic simulations and any context that requires a simple and convenient mathematics library.

GraphThing is a tool that allows you to create, manipulate and study graphs. These "graphs" are mathematical objects that describe relationships between sets; they are not 2D plots, charts, or anything similar to that.

Grace is a WYSIWYG 2D plotting tool for the X Window System and M*tif, successor of ACE/gr (Xmgr). A few of its features are: * User defined scaling, tick marks, labels, symbols, line styles, colors. * Batch mode for unattended plotting. * Read and write parameters used during a session. * Polynomial regression, splines, running averages, DFT/FFT, cross/auto-correlation. * Exports high-resolution graphics to (E)PS, PDF, MIF, and SVG formats * Supports cross-platform PNM, JPEG and PNG formats While grace has a convenient point-and-click interface, most parameter settings and operations are available through a command line interface (found in Data/Commands).
