Hi All,

Am new to Matlab and having a problem overloading subsref.

In short, I have a class that wraps a container.map. I want to overload the () operator to return instances of the referenced item in the map. Then access using the '.' operator. i.e.

a = MyClass(MyEnums.Enum1).Data

However, cannot get it working..

This is my current attempt

        function varargout = subsref(obj,S)
            switch S(1).type
                case '()'
                    [varargout{1:nargout}] = obj.Parameters(uint32(S(1).subs{1}));
                case '.'
                    [varargout{1:nargout}] = builtin('subsref', obj, S(1));
            end
        end
