dpnp.cumsum(x1, **kwargs)[source]

Return the cumulative sum of the elements along a given axis.

For full documentation refer to numpy.cumsum.

Limitations

Parameter x is supported as dpnp.ndarray. Keyword argument kwargs is currently unsupported. 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])
>>> result = np.cumsum(a)
>>> [x for x in result]
[1, 2, 7]
>>> b = np.array([[1, 2, 3], [4, 5, 6]])
>>> result = np.cumsum(b)
>>> [x for x in result]
[1, 2, 6, 10, 15, 21]
