It includes complex, real, +symmetric, and parallel transforms, and can handle arbitrary array sizes +efficiently. FFTW is typically faster than other publically-available FFT +implementations, and is even competitive with vendor-tuned libraries. + +There are several machine-dependent optimizations that can be enabled in order +to generate SIMD code; take a look in fftw.SlackBuild to enable them. |
