GNU compilers

Homepage: http://gcc.gnu.org/
Version: 3.3.5 (prerelease) License: GPL
Description: C/C++/Fortran compilers from GNU. Invoked using gcc/g++/g77 respectively.

GNU R

Homepage: http:http://www.r-project.org/
Version: 2.0.1 License: GPL and LGPL
Description: R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity.

Gnuplot

Homepage: http://gnuplot.sourceforge.net/
Version: 4.0 (patchlevel 0) Copyright: click here
Description: Gnuplot is a portable command-line driven interactive datafile (text or binary) and function plotting utility. Gnuplot supports various kinds of plots. In 2D, it can draw line, point, dot, box, histogram graphs or vector fields. In 3D, it supports line, point and dot surfaces, with or without hidden line removal. It supports color or grayscale surfaces and maps, even for non-equidistant and non-rectangular 3D data, otherwise it offers data gridding.

Octave

Homepage: http://www.octave.org
Version: 2.1.64 License: GPL
Description: GNU 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 using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.

Octave has extensive tools for solving common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations. It is easily extensible and customizable via user-defined functions written in Octave's own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages.
