  "Description": "Provides a wrapper for several 'FFTW' functions. This\npackage provides access to the two-dimensional 'FFT', the\nmultivariate 'FFT', and the one-dimensional real to complex\n'FFT' using the 'FFTW3' library. The package includes the\nfunctions fftw() and mvfftw() which are designed to mimic the\nfunctionality of the R functions fft() and mvfft(). The 'FFT'\nfunctions have a parameter that allows them to not return the\nredundant complex conjugate when the input is real data.",
