Unwrap by changing deltas between values to 2*pi complement.
Unwrap radian phase p by changing absolute jumps greater than discont to their 2*pi complement along the given axis.
p : array_like
discont : float, optional
axis : int, optional
out : ndarray
If the discontinuity in p is smaller than pi, but larger than discont, no unwrapping is done because taking the 2*pi complement would only make the discontinuity larger.
>>> phase = np.linspace(0, np.pi, num=5) >>> phase[3:] += np.pi >>> phase array([ 0. , 0.78539816, 1.57079633, 5.49778714, 6.28318531]) >>> np.unwrap(phase) array([ 0. , 0.78539816, 1.57079633, -0.78539816, 0. ])
