Matlab Compiler SDK - Export Class to Python

Hi,
I've tried Matlab Compiler SDK to export code in Python and it seems to work pretty well.
I'd like to export some object oriented code but can't figure out how to use the generated Python module.
Say I export a class called "ClassA". Then I can initialize the generated module, and instantiante "ClassA" which return a "matlab.object".
After that, I don't know how to call the object methods. The functions does not exist in the object nor in the module. How can I do?
Matlab
classdef MatlabClassA
properties
c
end
methods
function obj = MatlabClassA(a,b)
obj.c = a + b;
end
function x = get_val(self)
x = self.c;
end
end
end
Python
import MatlabClassAModule
handle = MatlabClassAModule.initialize()
a = handle.MatlabClassA(10,20) # Creates an object
x = a.get_val() # does not exit. Ho do I do?
Thank you

This might be late, but you cannot access matlab objects from python as far as I know.
The only workaround I know is, you pass this object to a matlab function and access its methods and attributes there. If you alter the object you can return it anew and "use" it in your python code. So in your example you would write an extra matlab function:
function value = get_val_from_object(myobject)
value = myobject.get_val()
end
and then access it like so:
handle = MatlabClassAModule.initialize()
a = handle.MatlabClassA(10,20)
x = handle.get_val_from_object(a)

Hi Pier,
You can utilize MATLAB "Handle" class to create an object and call its methods in Python. For a detailed guide on how to make your MATLAB class a "Handle" class and utilize it within Python, you can refer to the discussion link provided below:-
For more information on how to work with MATLAB "Handle" objects in Python, you can utilize the documentation provided below:-
