How do I get a Matlab UI (app) to call another UI so that it appears that my app has multiple pages?

I am looking for a code example that will show me how to call another UI. I can not find any decent examples of this online. I have been trying to get a push button to call this other UI.

classdef App1 < matlab.apps.AppBase
    % Properties that correspond to app components
    properties (Access = public)
        UIFigure  matlab.ui.Figure
        Button    matlab.ui.control.Button
    end
    methods (Access = private)
        % Button pushed function: Button
        function ButtonPushed(app, event)
%            (WHAT GOES HERE TO CALL OTHER UI?) <---------------- 
        end
    end
    % App initialization and construction
    methods (Access = private)
        % Create UIFigure and components
        function createComponents(app)
            % Create UIFigure
            app.UIFigure = uifigure;
            app.UIFigure.Position = [100 100 640 480];
            app.UIFigure.Name = 'UI Figure';
            setAutoResize(app, app.UIFigure, true)
            %
            % Create Button
            app.Button = uibutton(app.UIFigure, 'push');
            app.Button.ButtonPushedFcn = createCallbackFcn(app, @ButtonPushed, true);
            app.Button.Position = [271 264 100 22];
        end
    end
end

Thank you to anyone who helps!

There are two possibilities:

a) create a new "Tab" in your existing GUI with uitab

https://de.mathworks.com/help/matlab/ref/uitab.html

b) just call the other Gui in the button press function like you would call any script or function.

c) About passing data or variables.

• You could pass the variables directly (depending on how your GUI is written)
• Please DON'T use global variables to share the content
• Use "setappdata" instead
• Or write your data to a temporary *.mat file that you load in the second GUI
• It might be possible to nest the second GUI within the first one, although I'm not 100% sure if this will work.
• if all else fails use "assignin" and send the vars to base workspace
