Provide convenient tools for mathematical related experiment, simulation, graphics and other requirements.

An object oriented Math library written in C++. This library contains set of template classes that are ready to be used. Currently a 2D Matrix, modular arithmetic, vector, and complex numbers are present. These systems can work together, you can create a matrix of complex numbers. Iterators for matrix and vector classes will be added soon. Please use SVN to access current version.

MathPro is a math program capable of performing complex operations. It is particularly useful for Algebra students of all levels. It performs many operations including solving quadratic equations.

An application that allows you to solve mathematical examples

Maximally flat (maxflat) digital filter design in Java, with arbitrary numbers of poles and zeros. "Maximally flat" means that the magnitude frequency response has the maximum number of vanishing derivatives at 0 and pi.

Maztrix is a matrix library and program (written in ANSI C++) for computing matrix calculations. Maztrix can find determinants, row reduce, and much more.

R-package to perform analysis of landmark based geometric morphometrics. Installation instructions: https://github.com/zarquon42b/Morpho/blob/master/README.md

NEW OPTIMIZATION TECHNOLOGY & PLANNING EXPERIMENT. Technology is designed for multidimensional optimization practical problems with continuous object functions. Technology higher efficiency than traditional optimization methods.

GraphiBuilder 1.0.1.9 version is released. Please note that the plugin is intended for 32-bit version of Notepad++ only. The "deriv" function is implemented. For example, the following formula: deriv ("sin x", "x", 0.01) draws derivative of "sin x" function graph using "x" as x variable. Third parameter is optional and specifies the accuracy. The latest version is powered by high-precision mode which makes calculation the overlaps much more accurate. Polar coordinate system max angle is now adjustable. The plugin builds any number of math graphs, locates its intersections and extremes, makes the report. The plugin is based on DBGP Plugin for Notepad++ by Damjan Zobo Cvetko

Various computational physics projects for the Mac / GNUStep platforms.

Numerics Library is a collection of routines to do numerical and statistical computations. Included in this library are routines to solve linear systems of equations, generate random numbers, compute values for random variables, and much more.

Octave GTK+ is a Octave binding for GTK+, to help develop GUI programs from Octave, with GTK+. It aims to aid fast creation of scientific programs that need GUI's as well as number crunching power. We will also simulatneously work on a GUI for Octave

Develop finite element stress analysis programs, that work with free cad systems(Maybe QCad). Right now there's only a 2d gridded structure analysis prog with a crappy interface, written mainly in octave.

We present the package Optimizer, aimed at constructing and optimizing general mathematical models of phenomena of versatile nature. It is written in the Matlab algorithmic language and is executed in the Matlab environment with partial functionality in Octave. The convenient visual interface and the detailed manuals are provided. The main benefit of the package is its capability to construct models of any level of complexity in a block-by-block manner. Elementary model blocks can be collected in libraries, and we have already written many such library programs. Many of these programs are already available along with the main package. Currently, the main focus of these is computational quantum mechanics, analysis and simulation of molecular spectra, and general-purpose approximants. The package provides the most reliable modern strategies for linear and non-linear model optimization, regularization, and hypothesis tests. Parallel computing is supported.

A Matlab software routine to perform Principal Component Analysis using Covariance, Correlation or Comedian as the criterion. Though, initially developed for experiments related to fretting wear but can be effectively used to interpret experimental data from any field. The attached files contain source code as well as a sample MATLAB (.mat) data file of 13 variables. It could be replaced to the data file of your choice. The code is open source but you are requested to give credits if used. Additionally, it also has some useful functions for exporting and generating publication quality figures for different kind of figures in MATLAB

The Open Source Probabilistic Networks Library is a tool for working with graphical models. It supports directed and undirected models, discrete and continuous variables, various inference and learning algorithms.

Pc Calculator is a clever note and formula editor combined with an advanced and strong scientific calculator. Being an editor it is extremely user-friendly allowing all possible typing and other errors to be easily corrected and fast recalculated.

PeCalc allows making calculations with integer fractions, complex numbers, complex matrices, rational functions and complex polynomials. It also allows making changes of numeric base, prime factor decomposition, solving linear equation systems, statistical and financial computations, rational fraction decomposition and plotting some control engineering graphs. PeCalc includes comprehensive user help in English and Spanish. Currently PeCalc runs on Android and MS Windows. A version for GNU Linux is planned for the near future. It has been developed in Object Pascal using Embarcadero Delphi. A Lazarus/Free Pascal version will be available soon too.

this will calculate the permutations you need numnbers letters or both

geofit is a tool to fit geometrical objects to point clouds and allows to calculate an errormap for both. it is useful for visualization of errors of a photogrammetric measurement.

Photon is a fully functional graphing calculator capable of numeric calculations as well as graphing functions, including parametric and polar graphs. In addition to regular graphing, Photon can plot integrals, first and second derivatives, tracing, animation, matrix math, and degree / radian mode. Photon can find roots, minimums and maximums, points of inflection, and it can fit several types of best fit lines and curves to data sets. Log and semi-log graphing are also available. Photon can save data to several file types, including images such as .jpg and .png. Display options are also available, including a dark / light theme for optimal visibility from a projector. Photon's primary goal is to be easy to use while retaining a feature-rich design. VB Gadgets brings you Photon - a parametric graphing calculator.
