igraph is a free software package for creating and manipulating undirected and directed graphs. It includes implementations for classic graph theory problems like minimum spanning trees and network flow, and also implements algorithms for some recent network analysis methods, like community structure search. igraph contains functions for generating regular and random graphs, manipulating graphs, assigning attributes to vertices and edges. It can calculate various structural properties, includes heuristics for community structure detection, supports many file formats.

ised is a command-line tool for generating number sequences and arithmetic evaluation. Unlike big gui-based software (e.g. Mathematica, Derive, Matlab, Octave,...) it is intended for use in shell scripting, together with gnu core utilities. Its main advantage is that all functions are generalized to operate on one-dimensional arrays. It can be used for loop indexing (much like seq), line-by-line arithmetic processing of files, floating point math for shells that don't support it natively, or interactively, as extended calculator.

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.

Lybniz is an easy to use mathematical function graph plotter using pyGTK.

Armadillo is a C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use. The syntax is deliberately similar to Matlab. Integer, floating point and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided through optional integration with LAPACK, or one of its high performance drop-in replacements (such as the multi-threaded MKL or ACML libraries). A delayed evaluation approach is employed (at compile-time) to combine several operations into one and reduce (or eliminate) the need for temporaries. This is accomplished through recursive templates and template meta-programming. Useful for conversion of research code into production environments, or if C++ has been decided as the language of choice, due to speed and/or integration capabilities.

muParser is an extensible high performance math parser library written in C++. It is based on transforming an expression into a bytecode and precalculating constant parts of it.

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.

LibTomMath provides highly optimized and portable routines for a vast majority of integer based number theoretic applications (including public key cryptography).
