# tensorplay.functional.add

Source: https://www.tensorplay.cn/docs/generated/tensorplay.functional.add.html

```python
tensorplay.functional.add(input, other, *, alpha=1, out=None) → Tensor
```

Adds other, scaled by alpha, to input.

$$\text{{out}}_i = \text{{input}}_i + \text{{alpha}} \times \text{{other}}_i$$

Supports [broadcasting to a common shape](/docs/notes/broadcasting.html#broadcasting-semantics),
type promotion, and integer, float, and complex inputs.

Parameters:

- input ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – the input tensor.

- other ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor) or Number) – the tensor or number to add to input.

Keyword Arguments:

- alpha (Number) – the multiplier for other.

- out ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor), optional) – the output tensor.

Examples:

```
>>> a = tensorplay.randn(4)
>>> a
tensor([ 0.0202,  1.0985,  1.3506, -0.6056])
>>> tensorplay.add(a, 20)
tensor([ 20.0202,  21.0985,  21.3506,  19.3944])

>>> b = tensorplay.randn(4)
>>> b
tensor([-0.9732, -0.3497,  0.6245,  0.4022])
>>> c = tensorplay.randn(4, 1)
>>> c
tensor([[ 0.3743],
        [-1.7724],
        [-0.5811],
        [-0.8017]])
>>> tensorplay.add(b, c, alpha=10)
tensor([[  2.7695,   3.3930,   4.3672,   4.1450],
        [-18.6971, -18.0736, -17.0994, -17.3216],
        [ -6.7845,  -6.1610,  -5.1868,  -5.4090],
        [ -8.9902,  -8.3667,  -7.3925,  -7.6147]])
