p = ZerosAndPoles.p()
Generate the complex Laplace variable p as a ZerosAndPoles transfer function. It can be used for generating like
ZerosAndPoles zp = p/(p^2 + p + 1)/(p + 1)
encapsulated function p import Modelica; import Modelica_LinearSystems2.ZerosAndPoles; output ZerosAndPoles zp(redeclare Real n1[1], redeclare Real n2[0, 2], redeclare Real d1[0], redeclare Real d2[0, 2]); end p;
