Description

This function plots a bode-diagram of the transfer function corresponding to the behavior of the state space system from iu'th element of the input vector u to the iy'th element of the output vector y.

Example

  Modelica_LinearSystems2.DiscreteStateSpace dss=Modelica_LinearSystems2.DiscreteStateSpace(
    A = [0.9048, 0.0,    0.0;
           0.0,   0.8187, 0.0;
           0.0,   0.0,    0.7408]
    B = [0.0;
          0.0906;
        -0.0864],
    C = [0.0, 1.0, 1.0],
    D = [1.0],
    B2 = [0.0;
          0.0;
          0.0],
