This unwraps a signal `p` by changing elements which have an absolute difference from their predecessor of more than ``max(discont, period/2)`` to their `period`-complementary values. For the default case where `period` is :math:`2\pi` and is ``discont`` is :math:`\pi`, this unwraps a radian phase `p` such that adjacent differences are never greater than :math:`\pi` by adding :math:`2k\pi` for some integer :math:`k`. Args: p (cupy.ndarray): Input array. discont (float): Maximum discontinuity between values, default is ``period/2``. Values below ``period/2`` are treated as if they were ``period/2``. To have an effect different from the default, ``discont`` should be larger than ``period/2``. axis (int): Axis along which unwrap will operate, default is the last axis. period: float, optional Size of the range over which the input wraps. By default, it is :math:`2\pi`. Returns: cupy.ndarray: The result array. .. seealso:: :func:`numpy.unwrap` )axisNrrrT)where)copydtype)cupyasarrayndimrdiffslicetuplenumpy result_typer issubdtypeintegerdivmodmodcopytoabsarraycumsum)pdiscontrrndddslice1r interval_highremboundary_ambiguous interval_lowddmod ph_correctupr<L/home/ubuntu/.local/lib/python3.10/site-packages/cupy/_math/trigonometric.pyunwrapjs2   r>)Nr)r&r r cupy._mathrrcreate_math_ufuncrrr arcsinarccosarctanrarctan2 create_ufuncdeg2radrad2degpir>degreesradiansr<r<r<r=sh             8
