Gain
This block implements a gain operation where the output is obtained by multiplying the gain parameter by the input. If the gain parameter is scalar, it is multiplied with every entry of the input to produce the output. If it is a matrix, an element-wise product is performed.

Description
The Gain block implements a gain operation where the output is obtained by multiplying the gain parameter by the input. If the gain parameter is scalar, then it is multiplied with every entry of the input to produce the output.
If it is a matrix, an element-wise product is performed. When input and parameter gain are both matrices, the dimensions should be identical or one must be scalar.
Inputs can be either real or complex.
Inputs are either scalar, vector or matrix.
To perform a matrix multiplication, use the MatrixGain block instead.
Parameters
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
gain | Gain | The gain value | Matrix | |
overflow | Do on overflow | This parameter defines the way overflow shoudl behandled for integer datatype. | String | 'Nothing' |
externalActivation | External activation | Specifies whether the block receives an external activation or inherits its activation through its regular input ports. When External Activation is selected, an additional activation port is added to the block. By default, external activation is not selected. | Number | 0 |
Ports
