Simulink: Class instance as output of a MATLAB function block

Hi All!

I'm new to simulink and I'm creating a Simple Model in which I add a MATLAB Function block.

The function is:

function [my_object] = CreateMyInstance()
    my_object = MyClass(); 
    my_object.a = 1; 
end

And MyClass is defined in external file MyClass.m and is the simple:

classdef MyClass < handle 
    properties 
        a
    end
    methods
        function obj = MyClass()
            obj.a = 0;
        end
    end
end

If I try to run the simulation I get the following error:

A top-level output parameter containing a class is not supported in MATLAB Function Block. Output parameter 'my_object' contains a class.

Can anyone help me on this issue or suggest another way to solve the problem? Is there a way to output the istance from the function ?

Thank you in advance

If involving object and class, use the MATLAB System block, although, you can't output an "object". You can utilize the methods and properties, but the output needs to be some types of data.
