numpy.unwrap(p, discont=3.141592653589793, axis=1)
[source]
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.
Parameters: 


Returns: 

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]) # may vary >>> np.unwrap(phase) array([ 0. , 0.78539816, 1.57079633, 0.78539816, 0. ]) # may vary
