- iarray.sum(a: IArray, axis: Optional[Union[int, tuple]] = None, cfg: Optional[Config] = None, **kwargs)#
Return the sum of array elements over a given axis.
axis¶ (None, int, tuple of ints, optional) – Axis or axes along which the reduction is performed. The default (axis = None) is perform the reduction over all dimensions of the input array. If this is a tuple of ints, a reduction is performed on multiple axes, instead of a single axis or all the axes as default.
sum – Sum of a. If axis is None, the result is a value. If axis is given, the result is an array of dimension a.ndim - len(axis). Its dtype is np.int64 for integers and bools, np.uint64 for unsigned integers and the dtype of
- Return type
IArray container or float
