tf.compat.v1.signal.ifftshift, `tf.compat.v2.signal.ifftshift`

tf.signal.ifftshift(
    x, axes=None, name=None
)

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

For example:

x = tf.signal.ifftshift([[ 0.,  1.,  2.],[ 3.,  4., -4.],[-3., -2., -1.]])
x.numpy() # array([[ 4., -4.,  3.],[-2., -1., -3.],[ 1.,  2.,  0.]])

Args
x	Tensor, input tensor.
axes	int or shape tuple Axes over which to calculate. Defaults to None, which shifts all axes.
name	An optional name for the operation.

Returns
A Tensor, The shifted tensor.
