# tensorplay.functional.neg

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

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

Returns a new tensor with the negative of the elements of input.

$$\text{out} = -1 \times \text{input}$$

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(5)
>>> a
tensor([ 0.0090, -0.2262, -0.0682, -0.2866,  0.3940])
>>> tensorplay.neg(a)
tensor([-0.0090,  0.2262,  0.0682,  0.2866, -0.3940])
```
