Fast Fourier transform.

Parameters: x (tuple) – (real, imag) where real is a Variable or an N-dimensional array storing the real part and imag is a Variable or an N-dimensional array storing the imaginary part.
Returns: Returns (ry, iy) where ry is the real part of the result and iy is the imaginary part of the result.
Return type: tuple

Note

Currently this function supports a tuple as input. It will support a complex numbers directly in the future.
