Module documentation for 0.1.3.6

This package provides bindings to the fftw library for one-dimensional vectors. It provides both high-level functions and more low-level manipulation of fftw plans.

We provide three different modules which wrap fftw's operations:

  • Numeric.FFT.Vector.Unnormalized contains the raw transforms;

  • Numeric.FFT.Vector.Invertible scales the backwards transforms to be true inverses;

  • Numeric.FFT.Vector.Unitary additionally scales all transforms to preserve the L2 (sum-of-squares) norm of the input.
