A basic quadratic equation calculator written in Java with a command-line interface. Handles fractions and imaginary roots. Thanks to Doug Lea at SUNY Oswego for his work on the Fraction class.
A 2-D inviscid flow and adjoint solver on unstructured triangular grids. It makes use of a vertex-centroid finite volume scheme which is second order accurate. The adjoint solver is developed using the automatic differentiation tool called TAPENADE.

Maximally flat (maxflat) digital filter design for Octave and Matlab. "Maximally flat" means that the magnitude frequency response has the maximum number of vanishing derivatives at 0 and pi. Handles arbitrary numbers of poles and zeros.

Fibonacci, to unix shell. Calculate large fibonacci numbers max. 255 digits, and writing to console. Program code writing in pascal language, and very small.
Bayesian Surprise Matlab toolkit is a basic toolkit for computing Bayesian surprise values given a large set of input samples. It is also useful as way of exploring surprise theory. For more information see also: http://ilab.usc.edu/
The Function Wizard is designed to provide a lightweight, fast, and easy to use application that will integrate, differentiate, calculate maxima and minima, etc. basic polynomials, as well as assist in other tedious polynomial tasks.
This is a small and fast library and command-line tool for manipulation of logic/boolean-algebra expressions, including proofing and simplification. A front-end using tigcc for Texas Instruments calculators is planned, too.
A MATLAB package to simulate sample paths of the solution of a Itô or Stratonovich stochastic differential equation (SDE), compute statistics and estimate the parameters from data.
A note of caution: SDE Toolbox is no more developed but it's still downloadable. Its inferential capabilities can be considered surpassed (at best). Actually the parameter estimation methods were already far from the state-of-art when the project began in 2007 (!). The considered implemented parametric and...
TAROT is a easy-to-use framework for Monte Carlo simulations in python. Calculations between different kinds of randomly distributed numbers are made as easy as basic arithmetics. Tarot provides an interactive graphical interface for interpretation.
These simple programs are for doing data reduction and then display of columns of tab delimited data. They are designed to be piped together so you can do multiple things at once. This means they typically read from stdin and output to stdout.
Topologia Digital (Digital Topology) is a project for the development of the practical exercises of the Digital Topology course in the Applied Mathematics Department of the Computer Science Faculty (Polytechnic University of Madrid, Spain).
Misc packages including a matrix application, a text based minesweeper, and simple console functions bundled to be run from a virtual console. Some packages are independently runnable. http://damf.sourceforge.net/ for more information.
Wurp is an RPN (Reverse Polish Notation) calculator, similar to the HP48 calculator. Wurp supports various platforms, including KDE and curses (and hopefully Windows eventually).
Console based application which should compile on any system supporting c++. Includes calculations like blood alcohol content, 1/4 mile run, liter conversion, etc.
If you ever needed to perform a variety of functions on a lot of different numbers, Funct is for you. It allows one to create, store, and modify functions which they can apply to numbers from the terminal. Funct is designed to be easy to use but powerful.
REPCAL (REverse Polish CALculator) is a light and fast calculator in RPN (reverse polish notation) mode for the console (command line). It is written in 180 lines of Python code, and can be used both interactively or inside shell scripts.
