MatrixGain
This block computes the matrix product of the block Gain parameter with the block input. A block parameter specifies whether the product is a left, right or element-wise multiplication. The inputs and the outputs must have the same datatype. In case of integer datatypes, a block parameter specifies the behavior of the block on overflow.

Description
The MatrixGain block computes the product of a matrix Gain by the input matrix u1, where the number of rows/cols of Gain is compatible with the size of u1.
The input/output datatype is defined by the type of the matrix Gain. It can take all the datatype.
Parameters
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
gain | Gain | This parameter defines the matrix Gain. That parameter can support all data types. | Matrix | |
overflow | Do on overflow | Defines the action in case of an overflow during the operation. Options are : "Nothing" (gives a normal, non satured result), "Saturate" (gives a saturated result), "Error" (gives an error message). | String | 'Nothing' |
mulmethod | Multiplication method | Defines how the matrix multiplication is performed. In the other words, it specifies whether the product is a left, right or element-wise multiplication. | String | 'Gain*u1' |
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
| Name | Type | Description | IO Type | Number |
|---|---|---|---|---|
Port 1 | explicit | input | 1 | |
Port 2 | explicit | output | 1 | |
Port 3 | activation | input | externalActivation |
