numpy.unwrap

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 thandiscont
to their 2*pi complement along the given axis.Parameters: -
p : array_like
-
Input array.
-
discont : float, optional
-
Maximum discontinuity between values, default is
pi
. -
axis : int, optional
-
Axis along which unwrap will operate, default is the last axis.
Returns: -
out : ndarray
-
Output array.
Notes
If the discontinuity in
p
is smaller thanpi
, but larger thandiscont
, no unwrapping is done because taking the 2*pi complement would only make the discontinuity larger.Examples
>>> 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
