tf.keras.ops.fft

Computes the Fast Fourier Transform along last axis of input.

tf.keras.ops.fft(
    x
)

Args
x	Tuple of the real and imaginary parts of the input tensor. Both tensors in the tuple should be of floating type.

Returns
A tuple containing two tensors - the real and imaginary parts of the output tensor.

Example:

x = (
    keras.ops.convert_to_tensor([1., 2.]),
    keras.ops.convert_to_tensor([0., 1.]),
)
fft(x)
(array([ 3., -1.], dtype=float32), array([ 1., -1.], dtype=float32))
