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

### 説明

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.

### パラメータ

`ann`

  ニューラルネットワークリソース。

`activation_steepness`

  The activation steepness.

`layer`

  Layer number.

### 返り値

成功した場合に `TRUE`、それ以外の場合に `FALSE` を返します。
