python package using matlab object handle

Dear All,

I would like to compile my matlab function to python package library. Thus, I make a function parser , i.e. loadObject, printObject, etc. from my matlab object handle.

However, is it possible to pass matlab object handle using matlab struct for python? I remember, I did that for my implementation in C using mwArray. Is there any similar library?

I can't using matlab engine since it requires matlab license

Thank you,

function var = loadObject()
    var.obj = matlabClass();
end

function printObject(var)
    printObject(var.obj);
end


classdef matlabClass < handle
    properties
        a = 1;
    end
        
    methods
        function obj = matlabClass()
        end
        function printObject(obj)
            disp(obj.a)
        end
    end
end



function TestScript()

    var = loadObject();

    printObject(var);
end

I got this error:
