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.

OpenFst is a library for constructing, combining, optimizing, and searching weighted finite-state transducers (FSTs). Weighted finite-state transducers are automata where each transition has an input label, an output label, and a weight. The more familiar finite-state acceptor is represented as a transducer with each transition's input and output label equal. Finite-state acceptors are used to represent sets of strings (specifically, regular or rational sets); finite-state transducers are used to represent binary relations between pairs of strings (specifically, rational transductions). The weights can be used to represent the cost of taking a particular transition. FSTs have key applications in speech recognition and synthesis, machine translation, optical character recognition, pattern matching, string processing, machine learning, information extraction and retrieval among others. Often a weighted transducer is used to represent a probabilistic model (e.g., an n-gram model, pronunciation model). FSTs can be optimized by determinization and minimization, models can be applied to hypothesis sets (also represented as automata) or cascaded by finite-state composition, and the best results can be selected by shortest-path algorithms.

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.

Cadabra is a symbolic computer algebra system (CAS) designed specifically for the solution of problems encountered in field theory. It has extensive functionality for tensor computer algebra, tensor polynomial simplification including multi-term symmetries, fermions and anti-commuting variables, Clifford algebras and Fierz transformations, component computations, implicit coordinate dependence, multiple index types and many more. The input format is a subset of TeX.

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.

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.

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 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.

CLooG is a free software and library generating loops for scanning Z-polyhedra. That is, it finds a code (e.g. in C, FORTRAN...) that reaches each integral point of one or more parameterized polyhedra. CLooG has been originally written to solve the code generation problem for optimizing compilers based on the polytope model.

Eigen is a C++ template library for linear algebra (vectors, matrices, and related algorithms).

A unit converter that can combine the units any way you want. If you want to convert from inches per decade, that's fine. Or from meter-pounds. Or from cubic nautical miles. The units don't have to make sense to anyone else.
