Information

Syntax

result = DiscreteTransferFunction.Analysis.denominatorDegree(dtf)

Description

Function Analysis.denominatorDegree calculates the degree of the denominator polynomial of a discrete transfer function.

Example

   TransferFunction z = Modelica_LinearSystems2.DiscreteTransferFunction.z();
   Modelica_LinearSystems2.DiscreteTransferFunction dtf=(z+1)/(z^2+z+1);

   Real dDegree;

algorithm
  dDegree := TransferFunction.Analysis.denominatorDegree(dtf);
//  dDegree = 2
