`numpy.fft:ifftshift`

source: build-install/usr/lib/python3.14/site-packages/numpy/fft/_helper.py :77

Signature

def ifftshift ( x , axes = None )

Summary

The inverse of fftshift. Although identical for even-length x, the functions differ by one sample for odd-length x.

Parameters

x : array_like: Input array.
axes : int or shape tuple, optional: Axes over which to calculate. Defaults to None, which shifts all axes.

Returns

y : ndarray: The shifted array.

Examples

import numpy as np
freqs = np.fft.fftfreq(9, d=1./9).reshape(3, 3)
freqs
np.fft.ifftshift(np.fft.fftshift(freqs))
