Discrete Fourier transforms

fft(da[, n, dim, norm, parallel])	Compute the discrete Fourier Transform along a given dimension.
ifft(da[, n, dim, norm, parallel])	Compute the inverse of fft.
rfft(da[, n, dim, norm, parallel])	Compute the discrete Fourier Transform for real inputs along a given dimension.
irfft(da[, n, dim, norm, parallel])	Compute the inverse of rfft.
