Colt provides a set of Open Source Libraries for High Performance Scientific and Technical Computing in Java http://acs.lbl.gov/~hoschek/colt/ This project starteda as a port of the Colt core library to C#, but contains additional features.

System independent command line calculator written in C (C99 standard). Expression is first converted to Reverse Polish Notation and then evaluated.

Ever had a bunch of ASCII data that you would like to have a quick look at in frequency domain, but don't want to fire up some bulky analysis software package just for that? Well, I have... So I wrote this tiny tool. It is based on fftw (www.fftw.org) and boost's program options (boost.org). cli-fft is really simple: All it does is to receive ASCII data from a file or standard in, FFT it and write out the result into a file or to standard out.

A toolkit for processing and visualising sensor data in real time with support for use with embedded platforms.

- MixtureModel_v1r1: overlapping community algorithm [3], which includes novel partition density and fuzzy modularity metrics. - OpenMP versions of algorithms in [1] are available to download. - Main suite containing three community detection algorithms based on the Modularity measure containing: Geodesic and Random Walk edge Betweenness [1] and Spectral Modularity [2].

The suite is based upon the fast community algorithm implemented by Aaron Clauset <aaron@cs.unm.edu>, Chris Moore, Mark Newman, and the R IGraph library Copyright (C) 2007 Gabor Csardi <csardi@rmki.kfki.hu>. It also makes of the classes available from Numerical Recipies 3rd Edition W. Press, S. Teukolsky, W. Vetterling, B. Flanne

CompLearn is a general-purpose compression-based machine learning system that uses data compression to learn or data mine patterns in arbitrary data.

Compact Mesh Generator, written in ANSI-C. Parallel and Serial versions.

This computer program is an exact emulation of a toy which was sold years ago called Magic Designer. There are 4 versions - MS Windows one written in Euphoria and C and one written for the Web for people who do not have a Windows computer. An Android version. And a new cross platform version.

A complex number class to deal with complex numbers. It will add, subtract, mutiply, divide, and raise a complex number to a power. It also has overloaded input and output streams to print and input complex numbers.

Complex Systems is a toolbox for SCILAB software. This toolbox measures some parameters for graphs representing complex systems: degree distribution, average neighboring degree, average clustering, and shell index (from k-core decomposition).

A tool written in C++ to generate very large Fibonacci numbers using the primary recursive formula: F(n) = F(n-1) + F(n-2) n > 1; F(1) = 1, F(0) = 0.

Java program for computations with values expressed in terms of physical or other units. Supports complicated mathematical expressions and user-defined functions. Invoked from scripts, line command, or as GUI. Extensive units data base.

ConcordeDSP -- A user friendly, Open Source, GUI-based DSP filter design and waveform analysis environment

Preference (or approval) ballot tabulation to select winner(s) of election contests or rank decisions. Uses dropping cost minimization to combine two Condorcet methods: Cloneproof Schwartz Sequential Dropping and Tideman's Ranked Pairs.

A program for finding the congruencies of a groupoid

Evalute mathematic expression in console. Released many functions and operations.

This is a Calculator useful for the construction trades. Right now this is in alpha stage. Currently it incorporates for units; feet, inches, feet and inches, square feet, square inches, square yards, cubic feet, cubic inches, cubic yards, and plain decimal. For operations you can add, subtract, multiply, and divide. You can also use () for grouping. The program uses a GUI. My future plans include incorporating; a command line interface, figuring roof slopes, rafters and stairs.

"kdiv" is a generator of routines for optimized division by an integer constant based on the work presented in H.S. Warren's "Hacker's Delight". "kdiv" can be used to emit a generic assembly or C implementation of (signed/unsigned) division.

Sympercon is a software package for computational bifurcation analysis of Hamiltonian relative periodic orbits.

The continuous medial representation is a method for object representation and shape analysis. Hosted on Sourceforge are the source code for routines that fit medial models to anatomical objects.

This is more one unit converter. But this will be the better! Multiplatform, probably using Qt and C++, unit categories, many units to choose!!

A very simple unit converter written in rust, simple to use and fast too! 🙂 Currency converter is planned, and more features will probably come. You can contact me on X for support.

Its an example code of parallel implementation of Convex Envelop determination in a set of points on a 2 dimensional plane,using CUDA.
