cannam@95 1 FFTW is a free collection of fast C routines for computing the
cannam@95 2 Discrete Fourier Transform in one or more dimensions. It includes
cannam@95 3 complex, real, symmetric, and parallel transforms, and can handle
cannam@95 4 arbitrary array sizes efficiently. FFTW is typically faster than
cannam@95 5 other publically-available FFT implementations, and is even
cannam@95 6 competitive with vendor-tuned libraries. (See our web page for
cannam@95 7 extensive benchmarks.) To achieve this performance, FFTW uses novel
cannam@95 8 code-generation and runtime self-optimization techniques (along with
cannam@95 9 many other tricks).

cannam@95 13 doc/FAQ/ directory in ASCII and HTML.
