Signature#

nabla.add(x: 'Array | float | int', y: 'Array | float | int') -> 'Array'

Description#

Adds two arrays element-wise.

This function performs element-wise addition on two arrays. It supports broadcasting, allowing arrays of different shapes to be combined as long as their shapes are compatible. This function also provides the implementation of the + operator for Nabla arrays.

Parameters#

  • x (Array | float | int): The first input array or scalar.

  • y (Array | float | int): The second input array or scalar. Must be broadcastable to the same shape as x.

Returns#

  • Array: An array containing the result of the element-wise addition.

Examples#

Calling `add` explicitly:

>>> import nabla as nb
>>> x = nb.array([1, 2, 3])
>>> y = nb.array([4, 5, 6])
>>> nb.add(x, y)
Array([5, 7, 9], dtype=int32)

Calling `add` via the `+` operator:

>>> x + y
Array([5, 7, 9], dtype=int32)

Broadcasting a scalar:

>>> x + 10
Array([11, 12, 13], dtype=int32)
