(synopsis "Wrapper for FFTW3")
(description
"This package provides a wrapper for several FFTW functions. It provides
access to the two-dimensional FFT, the multivariate FFT, and the
one-dimensional real to complex FFT using the FFTW3 library. The package
includes the functions @code{fftw()} and @code{mvfftw()} which are designed to
mimic the functionality of the R functions @code{fft()} and @code{mvfft()}.
The FFT functions have a parameter that allows them to not return the
redundant complex conjugate when the input is real data.")
