Information

Subtract two transfer functions (tf1 - tf2)

Interface

function subtract
  import Modelica_LinearSystems2.Math.Polynomial;
  import Modelica_LinearSystems2.TransferFunction;
  input TransferFunction tf1;
  input TransferFunction tf2;
  output TransferFunction result = (Polynomial(tf1.n)*Polynomial(tf2.d) - Polynomial(tf2.n)*Polynomial(tf1.d))/(Polynomial(tf1.d)*Polynomial(tf2.d));
end subtract;
