z = DiscreteTransferFunction.s()
Generate the complex variable z=exp(T*s) as a DiscreteTransferFunction. It can be used for generating like
DiscreteTransferFunction dtf = z/(3*z^2 + 2*z +2)
encapsulated function z import Modelica_LinearSystems2.Math.Polynomial; import Modelica_LinearSystems2.DiscreteTransferFunction; output DiscreteTransferFunction dtf(n = {1, 0}, d = {1}) "z"; end z;
