tf.signal.fftshift(
x, axes=None, name=None
)
This function swaps half-spaces for all axes listed (defaults to all). Note that y[0] is the Nyquist component only if len(x) is even.
For example:
x = tf.signal.fftshift([ 0., 1., 2., 3., 4., -5., -4., -3., -2., -1.])
x.numpy() # array([-5., -4., -3., -2., -1., 0., 1., 2., 3., 4.])
| Args | |
|---|---|
| x | Tensor, input tensor. |
| axes | int or shape tuple, optional Axes over which to shift. Default is None, which shifts all axes. |
| name | An optional name for the operation. |
| Returns |
|---|
| A Tensor, The shifted tensor. |
