# tensorplay.functional.sqrt

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

```python
tensorplay.functional.sqrt(input, *, out=None) → Tensor
```

Returns a new tensor with the square-root of the elements of input.

$$\text{out}_{i} = \sqrt{\text{input}_{i}}$$

Parameters:

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

Keyword Arguments:

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

Example:

```
>>> a = tensorplay.randn(4)
>>> a
tensor([-2.0755,  1.0226,  0.0831,  0.4806])
>>> tensorplay.sqrt(a)
tensor([    nan,  1.0112,  0.2883,  0.6933])
```
