**Header:** `ClikaRT/nn/generated/elementwise.h`  
**Inherits:** [`ClikaRT::nn::Module`](./Module.md)

Multiplies `input` by `other` elementwise with broadcasting, then the optional fused activation. The module form of [`ClikaRT::ops::mul`](../ops/mul.md#mul), which documents the full contract (shapes, dtypes, errors); construct once, then call it like a function.

## Member functions

### Mul() {#Mul}

<div class="api-signature">

`explicit` **`Mul`**([`MulOptions`](./MulOptions.md) `options` `=` `{}`)

</div>

Constructs the module from [`options`](./Mul.md#options) (every default when omitted).
