Parameters ---------- ar : array-like of rank N Input array. crop_width : {sequence, int} Number of values to remove from the edges of each axis. ``((before_1, after_1),`` ... ``(before_N, after_N))`` specifies unique crop widths at the start and end of each axis. ``((before, after),)`` specifies a fixed start and end crop for every axis. ``(n,)`` or ``n`` for integer ``n`` is a shortcut for before = after = ``n`` for all axes. copy : bool, optional If `True`, ensure the returned array is a contiguous copy. Normally, a crop operation will return a discontiguous view of the underlying input array. order : {'C', 'F', 'A', 'K'}, optional If ``copy==True``, control the memory layout of the copy. See ``np.copy``. Returns ------- cropped : array The cropped array. If ``copy=False`` (default), this is a sliced view of the input array.
