tf.keras.ops.fft

Computes the Fast Fourier Transform along last axis of input.

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

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))
