# numpy.unwrap

`numpy.``unwrap`(p, discont=3.1415926535897931, axis=-1)

  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 : | 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.

  `rad2deg`, `deg2rad`

  Notes

  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.

  Examples

      >>> 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.        ])
