fann_set_activation_steepness_layer — Sets the activation steepness for all of the neurons in the supplied layer number

### Description

function fann_set_activation_steepness_layer(resource `$ann`, float `$activation_steepness`, int `$layer`): bool

Set the activation steepness for all of the neurons in layer number `layer`, counting the input layer as layer 0.

It is not possible to set activation steepness for the neurons in the input layer.

### Parameters

`ann`
  Neural network resource.
`activation_steepness`

  The activation steepness.

`layer`

  Layer number.

### Return Values

Returns `true` on success, or `false` otherwise.
