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."
