The inverse of fftshift.
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.
