gdcalc is a financial, statistics, scientific and programmers
calculator for Unix. The GUI was written with glade(1) and uses the
Gnome/Gtk+ toolkit - so it may well be compatible with themes and
other whiz-bang features of those systems.
gdcalc has both Algebraic notation (ie. conventional, TI or Casio
style) and Reverse Polish Notation (RPN or Hewlett-Packard style).
If you've not heard of RPN before, you are probably familiar with
algebraic calculators. Very briefly, while simpler and more natural
to use, RPN calculators need some study eg. they have an Enter key
instead of the equals key.
This library provides a number of common functions and types useful in
statistics. We focus on high performance, numerical robustness, and use
of good algorithms. Where possible, we provide references to the
statistical literature.
The library's facilities can be divided into four broad categories:
* Working with widely used discrete and continuous probability
distributions. (There are dozens of exotic distributions in use; we
focus on the most common.)
* Computing with sample data: quantile estimation, kernel density
estimation, histograms, bootstrap methods, significance testing, and
autocorrelation analysis.
* Random variate generation under several different distributions.
* Common statistical tests for significant differences between samples.
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 fenv.
On supported architectures, change the rounding mode of the floating point
arithmetics (to nearest, up, down, to zero) or change the precision of the
arithmetical operations (single, double, double extended). Experimentally
test the properties of the floating point arithmetics.

This is image.
The Octave-forge Image package provides functions for
reading, writing, and processing images. The package supports
almost all image formats through the use of ImageMagick.
The package also provides functions for feature extraction, image
statistics, spatial and geometric transformations, morphological
operations, linear filtering, and much more.
CLEX (pronounced KLEKS) is a file manager with full-screen user interface.
It displays directory contents, including file status details, and provides
features like command history, filename insertion, or name completion, in
order to help users to create commands to be executed by the shell.
CLEX is versatile tool for system administrators and all users that utilize
the enormous power of the command line. Its unique one-panel user interface
enhances productivity and lessens the probability of mistake. There are no
built-in commands; CLEX is an add-on to your favorite shell.
Clutter-GStreamer (clutter-gst) is an integration library for using GStreamer
with Clutter.
Clutter is an open source software library for creating fast, visually
rich and animated graphical user interfaces. It uses OpenGL for drawing
primitives and has multiple backends, allowing its usage on different
platforms.
GStreamer is a streaming media framework, based on graphs of filters
which operate on media data. Applications using this library can do
anything from real-time sound processing to playing videos, and just
about anything else media-related. Its plugin-based architecture means
that new data types or processing capabilities can be added simply by
installing new plug-ins.

[ excerpt from developer's site ]
This is a collection of plugins written with the GStreamer framework.
Some features of these plugins are:
- Dynamically loaded plugins provide elements and media types,
demand-loaded via an XML registry, similar to ld.so.cache
- Element interface handles all known types of sources, filters,
sinks
- Capabilities system allows verification of element compatibility
using MIME types and media-specific properties
- Autoplugging uses capabilities system to complete complex paths
automatically
- Pipelines can be saved to XML and loaded back to working state
- Resource friendly plugins don't waste RAM

The goal of GstValidate is to be able to detect when elements are not
behaving as expected and report it to the user so he knows how things
are supposed to work inside a GstPipeline. In the end, fixing issues
found by the tool will ensure that all elements behave all together in
the expected way.
The easiest way of using GstValidate is to use one of its command-line
tools, located at tools/ directory. It is also possible to monitor
GstPipelines from any application by using the LD_PRELOAD gstvalidate
lib. The third way of using it is to write your own application that
links and uses libgstvalidate.
