Call class A method from class B using function handle?

Please see below example:

classdef MainClass
    properties
        Prop1
    end   
    methods
        function obj = MainClass()
            obj.Prop1 = ClassB;
            obj.Prop1.SetMethod(@MyMethod);
        end
        function MyMethod(obj)
            disp('MainClass MyMethod called')
        end
    end
end

classdef ClassB < handle
    properties
        UpdateMethod
    end
    methods
        function SetMethod(obj,newMethod)
            obj.UpdateMethod = newMethod;
        end
        function CallUpdateMethod(obj)
            obj.UpdateMethod();
        end
    end
end

>> x = MainClass;
>> x.Prop1.CallUpdateMethod;
Unrecognized function or variable 'MyMethod'.

Error in ClassB/CallUpdateMethod (line 10)
obj.UpdateMethod();

I'd like to call MainClass MyMethod from ClassB however am misunderstanding how this should be done. Any help would be appreciated. Thanks

        function obj = MainClass()
            obj.Prop1 = ClassB;
            obj.Prop1.SetMethod(@()obj.MyMethod);
        end

Thanks Matt, I couldn't figure this out from the docs. I'm still having an issue. Say MyMethod takes in an argument e.g. function MyMethod(obj, arg1). How should the function handle signature be?

[Matt J]

obj.Prop1.SetMethod(@(arg1)obj.MyMethod(arg1))

Got it, thank you!
