Calculate data entropy to benchmark compression algorithms
Entropy is a program that will calculate the entropy of a given set
of data. This program is mainly used to benchmark the efficiency
of existing or developing compression algorithms.
Software library containing FFT functions written in OpenCL
clFFT
a software library containing FFT functions written in OpenCL
clFFT is a software library containing FFT functions written in OpenCL. In
addition to GPU devices, the libraries also support running on CPU devices to
facilitate debugging and heterogeneous programming.
Marsaglia's Diehard Battery of Tests of Randomness
Diehard is a battery of tests for random number generators developed
by Dr. George Marsaglia of Florida State University Department of
Statistics. Originally developed for testing pseudo-random generators,
Diehard has since become a de facto standard for testing RNGs.
Euclidean geometry drawing language
A compiler which allows to typeset geometry figures within a (La)TeX
document. This program is also useful to convert such figures in EPS
format or in various other vector graphic formats.
Perl Data Language
PDL (``Perl Data Language'') gives standard perl the ability to
COMPACTLY store and SPEEDILY manipulate the large N-dimensional data
arrays which are the bread and butter of scientific computing.
The idea is to turn perl in to a free, array-oriented, numerical
language in the same sense as commerical packages like IDL and
MatLab. One can write simple perl expressions to manipulate entire
numerical arrays all at once. For example, using PDL the perl variable
$a can hold a 1024x1024 floating point image, it only takes 4Mb of
memory to store it and expressions like $a=sqrt($a)+2 would manipulate
the whole image in a few seconds.
A simple interactive shell (perldl) is provided for command line use
together with a module (PDL) for use in perl scripts.
Shell calculator
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.
Raster fonts pack for jsmath
Although it works best with the TeX fonts installed, jsMath canfall back
on a collection of image-based fonts (which can still be scaled or printed
at high resolution). This is a pack of those.
Scientific calculator for KDE
KCalc is a calculator which offers many more mathematical functions
than meet the eye on a first glance. Please study the section on
keyboard accelerators and modes in the handbook to learn more about
the many functions available.
Multi-purpose desktop calculator (backend library)
Qalculate! is a multi-purpose desktop calculator. It is small and simple to
use but with much power and versatility underneath. Features include
customizable functions, units, arbitrary precision, plotting, and
a user-friendly interface.
KDE 4 frontend to mathematical software
Cantor is a KDE Application aimed to provide a nice interface for
doing mathematics and scientific computing. It doesn't implement its
own computation logic, but instead is built around different backends.
