Information

Syntax

result = DiscreteZerosAndPoles.Analysis.evaluate(dzp,q)

Description

Function Analysis.evaluate evaluates the DiscreteZerosAndPoles transfer function at a given (complex) value of q. The transfer function G(z)=N(q)/D(q) is evaluated by calculating the numerator polynomial N(z) and the denominator polynomial D(q).

Example

  Complex j = Modelica_LinearSystems2.Math.Complex.j();
  DiscreteZerosAndPoles q = Modelica_LinearSystems2.DiscreteZerosAndPoles.q();
  Modelica_LinearSystems2.DiscreteZerosAndPoles dzp=(q+1)/(q^2+q+1);

  Complex result;

algorithm
  result := Modelica_LinearSystems2.DiscreteZerosAndPoles.Analysis.evaluate(dzp, j+1);
//  result = 0.538462 - 0.307692j
