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.
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. |
