Pass existing object to different class objects

Hi I have a object oriented programm so simulate different appliances.

I have a class object where the general settings of my programm are stored, so I don't have to save a lot of datas to every objec

If I store the object of my settings in the other object, do I generate everytime a "new" settingsobject and use a lot of space or will it be just a "pointer" to my existing object?

classdef appliance

properties

gens

% ...

end

methods

function obj = timeClass(gens)

%UNTITLED Construct an instance of this class

obj.gens = gens

end

% ...

end

end

gens = generalClassObject

appli = appliance(gens)

It will be a "pointer", until you make a change to one of the shared copies. Then, the specific property variables that you change will be unshared. See also,

But I use "handle" als the superclass of my settingsobject "gens" it will remain as a reference to the existing object, not a new copy of the object.

Have I understood it correct?
