Wrapper for FFTW3: Includes 1-D, Univariate and Multivariate, and 2-D 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 FFTW3. 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.
