Package Information

Description:
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.
