| Parameter | Description |
|---|---|
| sys | a LTI model. |
| A | State matrix: Nx-by-Nx matrix. |
| B | Input-to-state matrix: Nx-by-Nu matrix. |
| C | State-to-output matrix: Ny-by-Nx matrix. |
| D | Feedthrough matrix: Ny-by-Nu matrix. |
| E | Nx-by-Nx matrix. |
| Parameter | Description |
|---|---|
| Z | Invariant zeros: column vector. |
| nrank | Normal rank: positive integer. |
tzero function is employed to extract the invariant zeros of a Multiple Input, Multiple Output (MIMO) dynamic system described by the system model sys.
In cases where sys is a minimal realization, these invariant zeros coincide with the transmission zeros of the system.
A = [1 2; 3 4];
B = [1; 0];
C = [1 0];
D = 0;
