    MSU's Sparse Fourier Repository

    The Home of DMSFT, AAFFT, GFFT, and MSFFT.

    A collection of sparse Fourier transform codes developed by faculty at MSU. Currently codes for four different prototype sparse FFTs are here: 1.) DMSFT, implemented by Ruochuan Zhang. This is a fast, stable, noise robust, and *fully discrete* improvement on the ideas in GFFT below. It is THE BEST sparse FFT around!!! If you're looking for AAFFT, try this out first. 2.) AAFFT, implemented by Mark Iwen in 2008. This code is easy to use, and documented well, but not implemented...

    Coffee-Physics

    Coffee-Physics

    A simple, lightweight physics engine written in CoffeeScript

    Coffee-Physics is a minimalist physics engine written in CoffeeScript that favors approachable, creative-coding workflows over heavyweight simulation frameworks. It models motion with a particle system and uses simple constraints and behaviors—such as gravity, attraction/repulsion, drag, and springs—to create believable movement with very little code. The design is intentionally composable: you attach behaviors to particles or groups and let the update loop integrate positions, producing...

    RAtom

    solves nonlinear Kohn-Sham equation for the neutral atom.

    RAtom solves nonlinear Kohn-Sham equation for the neutral atom. The adaptive algorithm based on finite element method (FEM) is implemented. Discretization of the differential eigenvalue problem is done by finite element method with Lobatto polynomials as a basis functions. High order Gauss quadratures are applied in order to obtain the total energy of atom with absolut accuracy of 1E-6 hartree. Disctretization leads to generalized eigenvalue problem, which is solved by procedures from...

    stellarics

    Inverse Compton emission from heliospheres of sun and stars

    Cosmic ray electrons scatter on the photon fields around stars, including the sun, to create gamma rays by the inverse Compton effect. This program computes the spectrum and angular distribution of this emission. The software also includes general-purpose routines for inverse Compton scattering on a given electron spectrum, for example for interstellar or astrophysical source modelling. For further information see these publications: http://arxiv.org/abs/astro-ph/0607563,...
