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.
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.
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.
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.
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.
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.
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.
This module is meant to be an introduction to the internal operations of Neural
Networks. It lets the user create a single node in a neural net based on the
Perceptron model.
The rpn function will take a scalar or list of sclars which
contain an RPN expression as a set of comma delimited values and
operators, and return the result or stack, depending on context.
Number::Misc provides some miscellaneous handy utilities for handling
numbers. These utilities handle processing numbers as strings,
determining basic properties of numbers, or selecting a random number
from a range.
