## relu() {#relu}

<div class="api-signature">

[`Tensor`](../Tensor.md) **`relu`**([`Tensor`](../Tensor.md) `input`)

</div>

Rectified linear unit.

$$
\mathrm{relu}(x) = \max(0, x)
$$

**Throws**

- `ClikaRT::Error`: when the input's dtype is not served for this operation (the machine-readable reason rides `code_name()`).

**Returns:** a new tensor, same shape and dtype as `input`.

```cpp
auto y = ClikaRT::ops::relu(x);
```
