ContTransFunc
This block implements a continuous-time linear system that is defined by its rational transfer function (Numerator/Denominator). The transfer function must be proper meaning that the degree of numerator must not exceed that of the denominator. In the MIMO case, the numerator and denominator must be defined as cells (see OML tf2ssc function for details).

Description
This block realizes the transfer function of a continuous linear system.
This block implements a continuous-time linear system represented by its rational transfer function (Numerator/Denominator). The transfer function must be proper, meaning that the degree of its numerator must not exceed that of its denominator. In the SISO case, the input and output may be of arbitrary but equal size, in which case the SISO system is applied element-wise.
The block has one input and one output.
Parameters
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
num | Coefficients of the numerator polynomial | An mxn matrix where m is the size of the output, and n is the order of the numerator polynomial. Alternatively a cell may be used in the MIMO case. | ||
den | Coefficients of the denominator polynomial | This parameter sets the denominator of the transfer function. This must be a polynomial. Alternatively a cell is used in the MIMO case. |
