Algomath is a portable 32bit integer Arithmetic C Library with prime numbers and numbers manipulation algorithms. Optional fast assembly language alternatives (NASM source) for prime numbers time-critical functions are also included for the Intel-x86 rang

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/

My personal computing suite provides some programs I developed as a hobbyist and currently include a lambda calculus interpreter and a calculator which solves arithmetic expressions; both are written in C++.

Binary Converter NET is a program created in vb.net to convert numeral systems, such as: convert binary to decimal, hexadecimal to octal or octal to binary and vice versa. Also the program supports many more conversions and simple program log which shows your calculations. This program can work without install but the Microsoft .NET Framework is required.

The Biopsychology Nonlinear Toolbox is a MATLAB toolbox that combines established analysis routines in one easy to use graphical user interface.

bjsim is a blackjack simulator, designed to test various basic (noncounting, total, noncompositional) strategies under various conditions: number of decks, game rules (double after split, dealer hitting soft 17, etc.).

BlowfishVHDL - free fully synthesizable Blowfish encryption algorithm hardware implementation.

This toolbox computes the parameters of the Bouc–Wen–Baber–Noori hysteresis model using Multiobjective optimization evolutionary algorithms (MOBEAs). The toolbox uses the NSGA − II algorithm, which is an elitist non–dominated sorting EA. The toolbox uses the original NSGA-II algorithm developed by Prof. Kalyanmoy Deb, which can be download from: http://www.iitk.ac.in/kangal/codes.shtml Prof. Deb allowed me to use and post this toolbox. For further information about the toolbox read the documentation and the following papers: - Kalyanmoy Deb, Sameer Agrawal, Amrit Pratap, T Meyarivan.

Command-line calculator with many features: - Syntax and error highlighting - Text representation of numbers (English, French, Czech) and Greek numerals - Modes for angles (Radians, Gradians, Cycles and Degrees) - Chart for single variable "x" etc.

Development of a common “open source” tool for assessing the accuracy of parameter estimates collected within the framework of the DCR (EU Regulation 1639/2001 and 1581/2004)

CPPLapack is a c++ class wrapper for BLAS, LAPACK and PARDISO. Its special features are the followings. [1]User-friendly interface [2]Hi-speed matrix calculations using BLAS and LAPACK [3]Minimized number of copy times using Smart Temporary system

Citrus is a library and suite of demo applications for converting numbers with units into numbers with different units.

Crispy Plotter is a function graph plotter for mathematical functions, featuring high drawing speed and an intuitive interface that is fun to use.

Descend is an open source program for drawing 3D surfaces from parametric equations. It uses a custom, very fast language called Misc to calculate the geometry. It also uses OpenGL to render scenes with high quality shaders. Website: https://descend.mimec.org/

Dynamis is a simple ODE solver implemented in C for studying dynamical systems (e.g. population biology).

Easy Funktion is an easy to use function plotter that supports complex numbers as well as real numbers. Additional features are equation solving, approximation functions and a built in pocket calculator.

Ellipt2d is a finite element program for solving second order, real and complex, two-dimensional elliptic problems with user-defined operators. Because Ellipt2d is written in Python, the code can easily be adapted for specific problems.

A Scheme (guile) interface to a local version of the Encyclopedia of integer Sequences with many features for complex queries. URL of the encyclopedia (where the database can be downloaded from) is: www.research.att.com/~njas/sequences/

Esos is a GTK2-based program for converting values expressed in one unit into another. It supports conversion between multiple types of units, falling into categories such as temperature, distance, volume, mass, etc.

FFFF is the fastest Win32/OSX/Linux/IRIX Mandelbrot generator. Features OpenGL, realtime zoom, SSE/AltiVec QuadPixel, SSE2/3DNow! DualPixel calc, FPU per pixel calc, GPU asm (Fragment/Vertex) calc, multiprocessor support, and benchmarking. Opt asm code!

This software computes Gauss-Legendre quadrature nodes and weights using the formulas developed in "Iteration-Free Computation of Gauss-Legendre Quadrature Nodes and Weights", I. Bogaert, published in the SIAM Journal of Scientific Computing (Permalink: http://dx.doi.org/10.1137/140954969). The key features are: - Speed: due to the simplified formulas and the O(1) complexity computation of individual Gauss-Legendre quadrature nodes and weights. The latter also makes this software perfectly compatible with parallel computing paradigms. - Accuracy: the error on the nodes and weights is smaller than a few ulps (see the paper for details).

The Free Finite Element Package is a library which contains numerical methods required when working with finite elements. The goal of FFEP is to provide basic functions for approximating the solution of elliptic and parabolic PDEs in 2D. Until 2016 FFEP was developed using C. Science 2016 the language was switched to GNU Octave with some C Mex-Functions. Mesh generation or import is not part of FFEP. We recommend the use of Gmsh.
