WebDescription. XFFT (for eXtended Fast Fourier Transform) is a Yorick extension to uniformely interface between various implementations of FFT (notably FFTW, the Fastest Fourier Transform in the West, and, in the future, CFFT based on Swarztrauber routines) and benefit from multi-threading, complex-to-real and real-to-complex transforms, etc. http://www.fftw.org/download.html

Webfftw2 - Fast Fourier Transform library (version 2) FFTW is a C subroutine library for computing the Discrete Fourier Transform (DFT) in one or more dimensions, of both real and complex data, and of arbitrary input size. We believe that FFTW, which is free software, should become the FFT library of choice for most applications. Our benchmarks, WebThe simplest way to compile FFTW on Windows is probably to install the free MinGWUnix environment so that you can use the GNU C compiler(gcc). There are a few options to our configurescript that we especially recommend on Windows: --disable-alloca: as of this writing (14 July 2009), the allocafunction seems to be broken under the 64-bit
