| Parameter | Description |
|---|---|
| sys | a LTI model. |
| Parameter | Description |
|---|---|
| numerator | polynomial coefficients: a row vector or as a cell array of row vectors. |
| denominator | polynomial coefficients: a row vector or as a cell array of row vectors. |
| Ts | Sampling time Ts, default: in seconds |
The function tfdata(sys) retrieves the matrix data numerator, denominator from the transfer function model (LTI array) represented by sys.
If sys is initially in the form of a state-space model (LTI array), it is automatically converted to the transfer function representation before extracting the matrix data.
numerator = 10;
denominator = [20, 33, 44];
sys = tf(numerator, denominator)
