Goodmorning everybody. Can you please help me with this problem?

I'm very new to MatLab's app designer and i was asking how i could share a variable in a GUI with a .m file.

In particulare, in the GUI, i have a numeric field and i want to share that value, once it has been insert, with a variable in an .m file; is it possible?

For semplicity, i'll post only the first code lines of th .m file:

clc
close all
clear all
app=Schedule; %Opening the GUI
tmp=app.Days; %BUT with this line i'll obviously get the value '0'

Here the code of the GUI:

    
    properties (Access = public)
        Days=0 %property name I want to share with .m file
    end
    
    % Callbacks that handle component events
    methods (Access = private)
        % Value changed function: DaysEditField
        function DaysEditFieldValueChanged(app, event)
            value = app.DaysEditField.Value;
            app.Days=value;
            %once the numeric fild has been chenged i would have it to be sent to a variable in the .m file (HOW?)
        end
        end
