array_fft

File Purpose: fft of numpy arrays.

Functions

fft1(array, dx[, axis, rad])	calculates fft along 1 dimension, as well as the corresponding frequencies.
fft2(array, dx, dy[, axes, rad])	calculates fft along 2 dimensions, as well as the corresponding frequencies.
fftN(array, ds[, axes, rad])	calculates fft along N dimensions, as well as the corresponding frequencies.
fftfreq_shifted(N, d, *[, rad])	returns the shifted frequencies corresponding to the fft of an array of length N,
ifftN(array[, df, axes, rad, x0, ds])	calculates inverse fft along N dimensions, as well as the corresponding positions.
ifftfreq_shifted(N[, df, rad, x0, ds, ...])	returns the shifted positions corresponding to the inverse fft of an array of length N.
