Description
This block creates a diagonal matrix from a 1D vector. If the length of the input vector is M then the output is an M-by-M matrix.
If the offset value is non-zero, the vector will be placed off-diagonal and the matrix size will be (M+|offset|)x(M+|offset|).
Parameters
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
offset | Diagonal offset | This used to create off-diagonal square matrix with the input vector. | Scalar | |
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 |
