We use the `LahnH` project in the following: In the first example, a 0-dimensional |SetItem| changes the value of the 0-dimensional parameter |hland_control.Alpha|: SetItem('alpha', 'hland_v1', 'control.alpha', 0) True alpha(1.0) array(2.0) alpha(1.0) alpha(2.0) In the second example, a 0-dimensional |SetItem| changes the values of the 1-dimensional parameter |hland_control.FC|: fc(278.0) fc(200.0) In the third example, a 1-dimensional |SetItem| changes the values of the 1-dimensional sequence |hland_states.Ic|: ic(nan, nan, nan, nan, nan) ic(2.0, 2.0, 2.0, 2.0, 2.0) ic(1.0, 2.0, 3.0, 4.0, 4.0) """
