fftwtools (version 0.9-2)
Description
This package is a wrapper for several fftw functions.
Please see the fftw package for additional tools. This package
provides access to the two-dimensional fft, the multivariate
fft, and the one-dimensional real to complex fft using fftw3.
The fft functions have a parameter that allows them to not
return the redundant complex conjugate when the input is real
data. The one-dimensional and multivariate fft functions can be
inverted without the redundant complex conjugate. Please see
the package fftw for general one-dimensional use of fftw, the
discrete cosine transform, and for more detailed use of
performance enhancing plans when using fftw.
