librsb is a library for sparse matrix computations featuring the Recursive
Sparse Blocks (RSB) matrix format. This format allows cache efficient and
multi-threaded (that is, shared memory parallel) operations on large sparse
matrices. The most common operations necessary to iterative solvers are
available, e.g.: matrix-vector multiplication, triangular solution,
rows/columns scaling, diagonal extraction / setting, blocks extraction, norm
computation, formats conversion. The RSB format is especially well suited
for symmetric and transposed multiplication variants. Most numerical kernels
code is auto generated, and the supported numerical types can be chosen by
the user at build time.
librsb implements the Sparse BLAS standard, as specified in the BLAS Forum
documents.
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 io.
Input/Output in external formats.
Calcoo is a scientific calculator designed to provide maximum
usability. The features that make Calcoo better than (at least some)
other calculator programs are:
* Bitmapped button labels and display digits to improve readability.
* No double-function buttons.
* Undo/redo buttons.
* Copy/paste interaction with X clipboard.
* Both RPN (reverse Polish notation) and algebraic modes are available.
* Tick marks to separate thousands.
* Two memory registers with displays.
* Displays for Y, Z, and T registers.
* It is a purely scientific calculator.
Features that Calcoo lacks:
* Statistical mode.
* HEX mode.
Algae is a programming language for numerical analysis. It was written in
the Boeing Company to fulfill their need for a fast and versatile tool,
capable of handling large systems. Algae has been applied to interesting
problems in aerospace and related fields for more than a decade.
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,

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.
