Create transfer function model from zero-pole-gain data. This is just a stop-gap compatibility wrapper since zpk models are not yet implemented.

Inputs

sys

LTI model to be converted to transfer function.

z

Cell of vectors containing the zeros for each channel. z{i,j} contains the zeros from input j to output i. In the SISO case, a single vector is accepted as well.

p

Cell of vectors containing the poles for each channel. p{i,j} contains the poles from input j to output i. In the SISO case, a single vector is accepted as well.

k

Matrix containing the gains for each channel. k(i,j) contains the gain from input j to output i.

tsam

Sampling time in seconds. If tsam is not specified, a continuous-time model is assumed.

Optional pairs of properties and values. Type set (tf) for more information.

Outputs

sys

Transfer function model.
