class RFftwtools(RPackage):
    """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."""
