"""Wrapper for 'FFTW3' Includes: One-Dimensional Univariate,
One-Dimensional Multivariate, and Two-Dimensional Transform.
Provides a wrapper for several 'FFTW' functions. This package 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 fftw() and mvfftw() which are designed to
mimic the functionality of the R functions fft() and mvfft(). The 'FFT'
functions have a parameter that allows them to not return the redundant
complex conjugate when the input is real data."""
