How can I save objects of different classes that inherit all from the same superclass

Hi,

I currently have the problem, that I have implemented a program, where I save objects in an array. Now I have implemented another type of object that inherits from the same superclass as the other objects (superclass: node, subclasses: node_flow, node_heat) I want to save objects of both classes(node_flow and node_heat) in an array. when I want to create a list as followed: global_node_list(i) with a for loop I get an error that MATLAB is not able to convert from node_heat to node_flow. I know that I can use a cell array, but I do not want to change 50 different m-files. Is there any other possibility to save the objects?

If I understood your question correctly, this excerpt from the help is a starting point:

    matlab.mixin.Heterogeneous is an abstract class that provides support for the
    formation of heterogeneous arrays. A heterogeneous array is an array of objects 
    that differ in their specific class, but are all derived from or are instances 
    of a root class. The root class derives directly from matlab.mixin.Heterogeneous.
