Fourier transform methods are used to analyze functions and data sets to provide frequencies, amplitudes, and phases of underlying oscillatory components. Fast Fourier transform (FFT) methods offer speed advantages over evaluation of explicit integrals (EI) that define Fourier transforms. It has been shown recently that EI methods can be more accurate than FFT methods (Courtney and Courtney, A More Accurate Fourier Transform) for scientific data analysis and that EI methods can be implemented in reasonable times with modern computing power. This project makes the source code (and command line Windows executable) developed in that study openly available for scientific and engineering uses.

Originally intended for speed in certain operations, this has become a fuller featured statistics package for C++ developers.

Implementation of the A2RMS Algorithm for univariate densities defined for real values.

ABACUSES is A Bright Costless Universal Statistical End-user Software.

Substitution cipher cracker based on ant colony optimization metaheuristic. Includes GUI. Everything is in czech because this is a school project :(

A linux calculator which maintains the option of the simple text-based experience of bc while adding features like function declaration, registers, and a gtk+2.0 GUI. There are many predefined functions and constants. Graphing is one of many future plans.

ANGEL-Automatic differentiation Nested Graph Elimination Library is a template library using the Boost Graph Library and the Standard C++ Library; it provides sparse representations of c-graphs their dual line graphs and vertex, edge and face elimina

ANNJ, Another Neural Network for Java is a neural network framework for the Java programming language. It is still in an early development stage, currently supporting only feed-forward type networks, but will soon be able to handle many other types.

ANT is a lightweight implementation in C of a kind of artificial neural net called Multilayer Perceptron, which uses the backpropagation algorithm as learning method. The package includes an introductory example to start using artificial neural nets.

Interdependent Java frameworks: AMath (abstract numbers support); AFuzzy (fuzzy numbers and methods); AMathSys (flexible solvers of linear and nonlinear algebraic and differential equations); ADSM (multi-criteria ranking and grading of alternatives).

The Automated Parameter Estimation and Model Selection Toolkit is a fast, parallelized MCMC engine written in C for Bayesian inference (parameter estimation and model selection).

Ruby classes for arbitrary precision floating point and arbitrary precision complex numbers. Keeps track of accumulated error. Uses overloaded operators. Also some testing programs. Used with a Ruby version of sode (sode.rb).Ruby versions new

APXaoS is a version of the XaoS fractal zoomer combined with the GNU MP library. The hope is to improve precision and the maximum depth for zooming. It is branched off from XaoS 3.2.3 and GNU MP 4.2.2.

APreL++ stands for Arbitrary Precision Library for C++. It provides classes for arbitrary precision numbers. It is based on C++ string manipulation.

ASCEND is a modelling environment and solver for large or small systems of non-linear equations, for use in engineering, thermodynamics, chemistry, physics, mathematics and biology. Solvers for both steady and dynamic (NLA & DAE) problems, are provid

ASEP simulation library is specialized for simulations of Asymmetric Simple Exclusion Processes (ASEP) and its mutations like SSEP or TASEP based on a graph. It is consisted of agents, models, timers and graphs that forms united modelling enviroment ready for computer cluster use - all based on Zarja library.

A branch-and-prune method to find all solutions to systems of nonlinear equations. The number of variables must equal the number of equations. The variables must have proper lower and upper bounds. The solver has an interface to the AMPL environment.

From single or scientific calculator to structured programming environment (+- pascal): Input, graphic (display of functions; direct draw; display, capture, etc. of images) functions; tests, ... Ready: visual problems or blind users. See below in the web (http://atcalc.sourceforge.net/)

A Tiny Mathematical Speed Parser ATMSP is a portable C++ parser for mathematical expressions like "sin(x)+y^2" e.g. These may contain arbitrary numbers of functions, variables and constants. Major design goal was minimalistic size and maximum speed. Tiny 320 code-lines offer a parser plus bytecode-generator, 26 mathematical functions and 17 supported base-types including complex and arbitrary MPFR-multiprecision. Both parser and bytecode may run in threads. The usage of ATMSP is most simple - just include a single header in your own code and go. Reasonably experienced coders may implement other base-types like bool, SSE2, rationals or bigint's with a few changes. Have fun, Heinz van Saanen

This is an attempt to make a portable, efficient, and abstract set of C++ classes which manipulate algebraic expressions. I wrote it to explore C++ inheritance and polymorphism and it's extremely likely this project is the wrong solution for you.
