6 The Fastest Fourier Transform in the West is a C subroutine library
7 for computing the Discrete Fourier Transform (DFT) in one or more
8 dimensions, of both real and complex data, and of arbitrary input
9 size. It is becoming the FFT library of choice for most
10 applications. Benchmarks, performed on a variety of platforms, show
11 that FFTW's performance is typically superior to that of other
12 publicly available FFT software.
