Command line FFT
A simple command line utility to produce an FFT/IFFT of ASCII data
Ever had a bunch of ASCII data that you would like to have a quick look at in frequency domain, but don't want to fire up some bulky analysis software package just for that? Well, I have... So I wrote this tiny tool. It is based on fftw (www.fftw.org) and boost's program options (boost.org). cli-fft is really simple: All it does is to receive ASCII data from a file or standard in, FFT it and write out the result into a file or to standard out. -

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 very... -

A More Accurate Fourier Transform
Computes Accurate Fourier Transform via Explicit Integration not FFT
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...
