Check whether two linear discrete state space systems have identical matrices
encapsulated operator function '==' import Modelica; import Modelica.Math.Matrices.isEqual; import Modelica_LinearSystems2.DiscreteStateSpace; input DiscreteStateSpace dss1 "System 1"; input DiscreteStateSpace dss2 "System 2"; input Real eps(min = 0) = 0 "Two elements e1 and e2 of the two systems are identical if abs(e1-e2) <= eps"; output Boolean same "=true, if the two systems are identical"; end '==';
