- cupy.roll(a, shift, axis=None)#
Roll array elements along a given axis.
Elements that roll beyond the last position are re-introduced at the first.
a (ndarray) – Array to be rolled.
shift (int or tuple of int) – The number of places by which elements are shifted. If a tuple, then axis must be a tuple of the same size, and each of the given axes is shifted by the corresponding number. If an int while axis is a tuple of ints, then the same value is used for all given axes.
axis (int or tuple of int or None) – The axis along which elements are shifted. By default, the array is flattened before shifting, after which the original shape is restored.
