dpnp.ediff1d

dpnp.ediff1d(x1, to_end=None, to_begin=None)

The differences between consecutive elements of an array.

For full documentation refer to numpy.ediff1d.

Limitations

Parameter x1``is supported as :obj:`dpnp.ndarray`. Keyword arguments ``to_end and to_begin are currently supported only with default values None. Otherwise the function will be executed sequentially on CPU. Input array data types are limited by supported DPNP Data types.

Examples

>>> import dpnp as np
>>> a = np.array([1, 2, 4, 7, 0])
>>> result = np.ediff1d(a)
>>> [x for x in result]
[1, 2, 3, -7]
>>> b = np.array([[1, 2, 4], [1, 6, 24]])
>>> result = np.ediff1d(b)
>>> [x for x in result]
[1, 2, -3, 5, 18]
