## Member functions

### ELUOptions() {#ELUOptions}

<div class="api-signature">

**`ELUOptions`**() `=default`

</div>

<div class="api-declared">

Declared in `ClikaRT/nn/generated/activation.h`, line 207

</div>

### ELUOptions(double) {#ELUOptions-2}

<div class="api-signature">

**`ELUOptions`**(`double` `alpha`)

</div>

`ELUOptions(alpha)`: implicit, so `ELU(alpha)` reads like the function call.

</div>

### alpha(double) {#alpha}

<div class="api-signature">

[`ELUOptions`](./ELUOptions.md)`&` **`alpha`**(`double` `v`)

</div>

Sets [`alpha`](./ELUOptions.md#alpha), the negative-side saturation value.
