GGobi is an open source visualization program for exploring high-dimensional data. It provides highly dynamic and interactive graphics such as tours, as well as familiar graphics such as the scatterplot, barchart and parallel coordinates plots. Plots are interactive and linked with brushing and identification.

Gnuplot is a portable multi-platform command-line driven graphing utility. It was originally created to allow scientists and students to visualize mathematical functions and data interactively, but has grown to support many non-interactive uses such as web scripting. It is also used as a plotting engine by third-party applications like Octave. Gnuplot has been supported and under active development since 1986. This port installs extra files for TeX terminals (latex, epslatex, Tikz, etc).

It is also used as a plotting engine by third-party applications like Octave. Gnuplot has been supported and under active development since 1986. Gnuplot supports many types of plots in either 2D or 3D. It can draw using lines, points, boxes, contours, vector fields, surfaces, and various associated text. It also supports various specialized plot types. Gnuplot supports many different types of output: interactive screen terminals (with mouse and hotkey input), direct output to pen plotters or modern printers, and output to many file formats (eps, emf, fig, jpeg, LaTeX, pdf, png, postscript, ...). Gnuplot is easily extensible to include new output modes. Recent additions include interactive terminals based on wxWidgets (usable on multiple platforms), and Qt. Mouseable plots embedded in web pages can be generated using the svg or HTML5 canvas terminal drivers.

Mathomatic is a highly portable, general purpose CAS (Computer Algebra System). Mathomatic can: * Solve, simplify, and compare algebraic equations, * Perform calculus transformations, * Help with finite series analysis, * Perform complex number and polynomial arithmetic, * Generate efficient C or Java code from equations.

Mpc is a C library for the arithmetic of complex numbers with arbitrarily high precision and correct rounding of the result. It is built upon and follows the same principles as Mpfr. The library is written by Andreas Enge, Philippe Theveny and Paul Zimmermann and is distributed under the Gnu Lesser General Public License, either version 2.1 of the license, or (at your option) any later version. The Mpc library has been registered in France by the Agence pour la Protection des Programmes on 2003-02-05 under the number IDDN FR 001 060029 000 R P 2003 000 10000.

MPIR is an open source multiprecision integer (bignum) library forked from the GMP (GNU Multi Precision) project. It consists of much code from past GMP releases, in combination with much original contributed code. MPIR is constructed by a developer and vendor friendly community of professional and amateur mathematicians, computer scientists and hobbyists.

NTL is an object oriented library for number theory, written by Victor Shoup. It provides objects and methods for - arbitrary length integers - finite fields - polynomials over fields - extensions of fields. - vectors and matrices over extensions - finite rings Unless you define WITHOUT_GMP, NTL requires libgmp4.

OGDF (Open Graph Drawing Framework) is a self-contained C++ class library for the automatic layout of diagrams. OGDF offers sophisticated algorithms and data structures to use within your own applications or scientific projects. The library provides: * A wide range of graph drawing algorithms that allow to reuse and replace particular algorithm phases by using a dedicated module mechanism. * Sophisticated data structures that are commonly used in graph drawing, equipped with rich public interfaces. * Self-contained code that does not require any additional libraries (except for some optional branch-and-cut algorithms).

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.

PDAL is a BSD licensed library for translating and manipulating point cloud data of various formats. It is a library that is analogous to the GDAL raster library. PDAL is focussed on reading, writing, and translating point cloud data from the ever-growing constellation of data formats that are being developed for working with multi-dimensional emitted-pulse scanning systems. While PDAL is not explicitly limited to working with LiDAR data formats, its initial rollout is focused in that area.
