Runge
Runge is an Interactive Solver for Systems of Differential Equations
Runge is an Interactive Solver for Systems of Ordinary Differential Equations. It solves initial value problem (aka Cauchy problem). Few advantages Runge provides: It's fast. It utilizes BLAS and LAPACK libraries optimized for modern multi-core processors. It's interactive. It allows you to start a solution by mouse click on a plane. It's precise. It uses Runge Rule to adjust step length to satisfy required precision on each step. -

XYmath
XYmath is a GUI that creates, documents and explores y=f(x) curve fits
XYmath will find the "best" curve fit using either minimum percent error or minimum total error. It can search through common equations, an exhaustive search through thousands of equations, splines, smoothed splines, or non-linear equations input by the user. After fitting, XYmath will find roots, minima, maxima, derivatives or integrals of the curve. It will generate source code that documents and evaluates the fit in python, FORTRAN or EXCEL. Configurable plots are created using matplotlib that are of publication quality. ... -

Ada Lapack
A partial port of Lapack to Ada 2012
...The code is written in the form of a generic package and covers the Lapack routines for - Matrix determinant and inverse on general matrices, - Eigenvalues and eigenvectors of general, real and hermitian symmetric matrices, - Solutions of systems of equations for general, real and hermitian symmetric coefficient matrices, - Singular value decomposition for general matrices Also included is a set of functions (and two procedures) that provide a more familiar Ada style interface to the Lapack routines. See also AdaLAPACK (https://sourceforge.net/projects/adalapack/), a binding to the Fortran LAPACK. -

abc-sde
approximate Bayesian computation for stochastic differential equations
A MATLAB toolbox for approximate Bayesian computation (ABC) in stochastic differential equation models. It performs approximate Bayesian computation for stochastic models having latent dynamics defined by stochastic differential equations (SDEs) and not limited to the "state-space" modelling framework. Both one- and multi-dimensional SDE systems are supported and partially observed systems are easily accommodated. Variance components for the "measurement error" affecting the data/observations can be estimated. A 50-pages Reference Manual is provided with two case-studies implemented and discussed. ... -

SciSimulations
A package of science simulation scripts for web browsers.
SciSimulations is a library of JavaScript functions to visual demonstrate principals equations and math in science. The simulations will enable anyone to explore the equations in science, and make the math behind science more than just some numbers on a page. Currently SciSimulations uses the HTML5 Canvas elements so most web browsers will be able to run the simulations except the old versions of Internet Explorer. -

...Karl |1|, using a discrete approach for the approximation of level-set based curve evolution (implicit active contours). This is a novel (2005) and fast algorithm without the need of solving partial differential equations (PDE) while preserving the advantages of level set methods, such as the automatic handling of topological changes. Considerable speedups (×100) have been demonstrated as compared to PDE-based narrow band level-set implementations.

Math Simulator
A simulation software for numerical techniques.
Math Simulator is a java-based application which simulates various mathematical techniques.It is extremely useful for the Engineering students and for professionals. Most importantly, unlike most others Math Simulator is an Application rather than a java - library. So, user is not required to have any computer background. A Unique feature of Math Simulator is that it allows you to save queries for later reference. Hence you can save the problems along with their results. -

Simon0026bFXplugin
Fractal Extreme plugin for Simon Snake's 0026b formula
...http://www.fractalforums.com/fractal-exteme/another-fractint-formula-i-like/ This new and improved version has better large-bailout logic, smooth shading and variants absoluting (or not) different sides of the real/imaginary equations. The original formula I've termed a buffalo because it absolutes both real and imaginary. The Mandelbrot version does not absoluting, burning ship absolutes the imaginary and celtic absolutes the real.

Fractal Extreme plugin for Simon Snake's 0030a formula
http://www.fractalforums.com/plugins/another-formula-i-would-like-made-into-a-plugin/ This implements 4 variations on Simon's request, plus smooth shaded versions and Julias. The Buffalo version of the formula is closest to his request (though rotated 180 degrees). Buffalo absolutes both the real and imaginary side of the equations. Mandelbrot version does not abosulte either. Burning ship absolutes the imaginary side , Celtic absolutes the real.
