r-fftwtools 0.9-11 Wrapper for FFTW3
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
mvfftw() which are designed to mimic the functionality of the R functions
mvfft(). The FFT functions have a parameter that allows them to not return the redundant complex conjugate when the input is real data.
