| 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 |
| sysIn | LTI model. |
| Parameter | Description |
|---|---|
| sys | Output tranfer function system model. |
sys = tf(numerator, denominator) is used to create a continuous-time transfer function model.
It is defined by specifying numerator and denominator of the transfer function.
When you include the Ts parameter, it allows you to create a discrete-time transfer function.
Setting Ts to -1 indicates an unspecified sampling time, and, in this scenario, the input arguments are treated as if they pertain to a continuous-time system.
