FFTW is a collection of fast C routines to -compute the Discrete Fourier Transform in one or more dimensions. +FFTW is a free collection of fast C routines for computing the +Discrete Fourier Transform in one or more dimensions. 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. (See our web page for +extensive benchmarks.) To achieve this performance, FFTW uses novel +code-generation and runtime self-optimization techniques (along with +many other tricks). |
