GTKMathplot is an interactive plotting program based on GTK+ and the Cairo graphics library. It can display bidimensional curves, tridimensional curves, and surfaces from Cartesian or parametric equations describing the mathematical objects you would like to visualize. It is designed to be intuitive for high school students with good mathematical knowledge. University students of engineering, physics, mathematics, or natural sciences should need no explanation at all to start using it proficiently.

Nuiton-matrix is a Java library to manage multiple-dimensions matrices.

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.

eq2png is a short Perl script to easily convert
LaTeX equations into a PNG file. This is useful
for making Impress presentations with LaTeX
equations.

FooTex is software for converting LaTeX math
markup into MathML, HTML, or PNG. It is basically
just a wrapper for texvc and blahtex. It provides
some extra functionality, and gives a consistent
interface to the functionality of the two
underlying packages. The documentation is built
into the source code. When you install footex, the
documentation will be installed as a man page.

Math Objects is a math template library for C++
using generic programming techniques. It can
handle different kinds of mathematical objects in
a consistent way. The objects in the library
include matrices, polynomials, rational functions,
extended precision numbers, complex numbers, and
more. All of these can be handled like basic
numerical types like integers or floating point
numbers. One can access properties of a
mathematical type through a (partial)
specialization of a traits class for that type
(AlgebraicTraits).

BConv is a command line Python script that
converts between numbers in base 2..36. It is
modelled after a similar program written in C by
the author in 1996.

surf is a tool to visualize algebraic curves and algebraic surfaces. It is script-driven and has optionally a nifty GUI using the GTK widget set.

qliss3d renders 3D Lissajous figures (figures made
of a different sine function for each dimension)
with a Qt interface. Users can look at the figures
from any viewing position they like and even
"listen" to the sound of the figures.

PyWeather is a collection of weather related
modules that are capable of performing conversion
calculations for many common meteorological units.

Isoline Retrieval uses supervised statistical classification to retrieve isolines from cross-track scanning or similar satellites. It contains software to generate training data using collocation or radiative transfer simulations, as well as routines to interpolate the final fields using a variation of multi-linear interpolation or kernel estimation. The currently-supported satellites are the Advance Microwave Sounding Unit (AMSU) series and, to a lesser extent, the Global Ozone Measurement Experiment (GOME). An ambitious researcher, however, could easily adapt the codes to a similar satellite.
