The Fastest Fourier Transform in the West 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. It is becoming the FFT library of choice for most
|
|
applications. Benchmarks, performed on a variety of platforms, show
|
|
that FFTW's performance is typically superior to that of other
|
|
publicly available FFT software.
