finiteDiff
Program for solving the Schrödinger equation
This little set of programs compute the solutions to one and three dimensional Schrödinger equations with different potentials. Explicit, implicit and eigenvalue methods are included. The explicit and implicit method are provided in C++ whereas the matrix method is implemented as a MATLAB scipt. All these method use finite differences. -

...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. -

Fast Solver for Potential and LFFFs
This is a fast solver for global potential field in the Solar Corona
This is a fast solver for computing the potential and linear force-free field (LFFF) above the full photosphere with the line-of-sight synoptic magnetogram as input. The global potential field and the LFFF are dealt with in an unified way by solving a three-dimensional Helmholtz equation in spherical shell and a two-dimensional Poisson equation on the photosphere. The solver is based on a combination of the spectral method and the finite-difference scheme. In longitude direction the equation is transformed into Fourier spectral space and the resulted 2D equations in r–θ plane for the Fourier coefficients are solved by finite difference in a direct way. ... -

IMathSoft
The software for solving special problems of mathematics and physics
The project "FD-Method For Solving PDEs" contains the software for solving the nonlinear Klein-Gordon equations (see www.arxiv.org/abs/1203.5979 for more detail). The project "Infinite systems of matrix equations" consists in developing algorithms and software for solving systems of matrix equations. In the present version the project allows one to solve an infinite system of matrix equations which arises in the theory of stability preserving structural transformations of systems of second-order ODEs (see http://arxiv.org/abs/1204.1814). ... -
