tf.signal.ifftshift

TensorFlow 1 version View source on GitHub

The inverse of fftshift.

Aliases:

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.
