How to make a container class than is able to call all class functions and apply them on all contained objects?

I have a class 'classB' that contains multiple objects of classA as a property. classB contains the same methods as classA but applies them on all ClassA objects it contains. Is there a way to do this in a single classB function instead of adding them all with a for loop?

classdef ClassB
    properties
         ClassAObj{1:3} %cell containing multiple class A objects
    end
    methods
        function function1(ClassB)
             for k = 1:numel(ClassAObj)
                 obj.ClassAObj{k}.function1 
             end
        end
        function function2(ClassB)
             for k = 1:numel(ClassAObj)
                 obj.ClassAObj{k}.function2 
             end
        end
        function...        
    end
end


classdef ClassA
    methods
        function1
        function2
        function...
    end
end
