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).

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.
