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

```python
tensorplay.functional.asinh(input: Tensor, *, out: Tensor | None) → Tensor
```

Returns a new tensor with the inverse hyperbolic sine of the elements of input.

$$\text{out}_{i} = \sinh^{-1}(\text{input}_{i})$$

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([ 0.1606, -1.4267, -1.0899, -1.0250 ])
>>> tensorplay.asinh(a)
tensor([ 0.1599, -1.1534, -0.9435, -0.8990 ])
```
