Aspcud is a solver for package dependencies. A package universe and a request
to install, remove, or upgrade packages have to be encoded in the CUDF format.
Such a CUDF document can then be passed to aspcud along with an optimization
criteria to obtain a solution to the given package problem.
Asymptote is a powerful script-based vector graphics language that
provides a natural coordinate-based framework for technical drawing.
Labels and equations are typeset with LaTeX, for high-quality
PostScript output.
A major advantage of Asymptote over other graphics packages is that
it is a programming language, as opposed to just a graphics program:
it can therefore exploit the best features of script (command-driven)
and graphical user interface (GUI) methods.
Biggles is a Python module for creating publication-quality 2D scientific
plots.
It supports multiple output formats (postscript, x11, png, svg, gif),
understands simple TeX, and sports a high-level, elegant interface. It's
intended for technical users with sophisticated plotting needs.
The goal is to produce the best scriptable plotting program.
The octave-forge package is the result of The GNU Octave Repositry project,
which is intended to be a central location for custom scripts, functions and
extensions for GNU Octave. contains the source for all the functions plus
build and install scripts.
This is cgi.
Common Gatway Interface for Octave.
Chryzodus is a cross-platform graphical program drawing
beautiful and colorful chryzodes.
If you do not know what chryzodes are, take a look at
http://www.chryzode.org/. Then you will be able to explore
the world of chryzodes by yourself using Chryzodus.
But one does not even need to know much about chryzodes
to use Chryzodus and see beautiful images appear on the screen!

This is queueing.
The queueing toolbox provides functions for queueing networks and Markov
chains analysis. This package can be used to compute steady-state performance
measures for open, closed and mixed networks with single or multiple job
classes. Mean Valud Analysis (MVA), convolution and various bounding
techniques are implemented. Various transient and steady-state performance
measures for Markov chains can als be computed (including state occupancy
probabilities, mean time to absorption, time-averaged sojourn times), both
for continuous-time and discrete-time chains.
Maxima is a Common Lisp implementation of MIT's Macsyma system for
computer based algebra.
GOBLIN is a C++ class library focussed on graph optimization and network
programming problems. It deals with all of the standard graph optimization
problems discussed by textbooks and in courses on combinatorial optimization.
Today, GOBLIN provides strongly polynomial algorithms for the following graph
optimization problems:
- Shortest paths in graphs and digraphs with negative lengths.
- Negative cycles and minimum mean cycles.
- Strong and 2-connected components.
- Minimum spanning trees, arborescences and 1-trees.
- Maximum st-flows, feasible circulations and b-flows.
- Min-cost st-flows, b-flows and circulations.
- Assignment problems of any kind.
- 1-matchings, b-matchings, capacitated b-matchings, f-factors and
degree-constrained subgraphs.
- Directed and undirected Chinese postman problems, T-joins.
The library also includes methods for NP-hard problems, namely TSP, ATSP,
stable sets and graph colouring.
Mpexpr adds two new commands to Tcl, 'mpexpr' and 'mpformat'. Mpexpr works
much like Tcl's native 'expr', but does all calculations using an arbitrary
precision math package. Mpexpr numbers can be any number of digits, with any
decimal precision. Final precision is controlled by a Tcl variable
'mp_precision', which can be any reasonable integer, limiting only the
number of digits to the right of the decimal point.
Mpformat works much like Tcl's 'format', except it formats multiple
precision numbers in a variety of formats.
Mpexpr also includes most math functions provided by 'expr', as well
as several new functions. Mpexpr also supports Tcl variables and
nested evaluation, just like 'expr':
FreeMat is a free environment for rapid engineering and scientific
prototyping and data processing. It is similar to commercial systems
such as MATLAB from Mathworks, and IDL from Research Systems, but is
Open Source.
