Inheritence scope problem with superclass timeseries

Hi, I have a subclass inherited from timeseries who is named "Interpolable". I would like to extends the classname timeseries to add some properties and methods to it. In my "Interpolable" constructor (with no parameters), I instanciated the constructor of the superclass with no properties too: obj = obj@timeseries(). In a sub methods named: function initializeX(obj, Data, Time), the superclass are initiated with a vector of data and time like that: "obj.Data = Data" and "obj.Time = Time". The problem is that the initializeX returns me a new timeseries and don't memorize the new data within the object. What should I do?

classdef Interpolable < timeseries

    methods
        function obj = Interpolable()
            obj = obj@timeseries();
        end

        function initx(obj,Data, Time)
            obj.Data = Data;
            obj.Time = Time;
        end
    end
end

That's because timeseries is a value class. See Comparing Handle and Value Classes
