WebIf sum (x, axis=0) == 0 then hilbert (ihilbert (x)) == x. For even len (x), the Nyquist mode of x is taken zero. The sign of the returned transform does not have a factor -1 that is more often than not found in the definition of the Hilbert transform. Note also that scipy.signal.hilbert does have an extra -1 factor compared to this function.
