shampoo.fftshift(x, additional_shift=None, axes=None)[source] [edit on github]

Shift the zero-frequency component to the center of the spectrum, or with some additional offset from the center.

This is a more generic fork of fftshift, which doesn’t support additional shifts.


x : array_like

Input array.

additional_shift : list of length M

Desired additional shifts in x and y directions respectively

axes : int or shape tuple, optional

Axes over which to shift. Default is None, which shifts all axes.


y : ndarray

The shifted array.
