| 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. |
