Hi. I m new matlab app designer app. I create a numeric field and i ask input from user then i created automatically numeric field according to user input. (figure 2). How i can read values that where in created fields ?

Also, is there any different methods for creation fields automatically and adding as components.

classdef app8 < matlab.apps.AppBase
    % Properties that correspond to app components
    properties (Access = public)
        UIFigure           matlab.ui.Figure
        NumEditFieldLabel  matlab.ui.control.Label
        NumEditField       matlab.ui.control.NumericEditField
        Button             matlab.ui.control.Button
    end
    % Callbacks that handle component events
    methods (Access = private)
        % Button pushed function: Button
        %% %% %% %% %% %% %% %% %% %% %% !!!!!! 
        function ButtonPushed(app, event)
            for i = 1:app.NumEditField.Value
            eval(sprintf('app8.ef%d = uieditfield(app.UIFigure,"numeric")',i));
            eval(sprintf('app8.ef%d.Position = [180,350 - %d,31,22]',i,37*i))
            end
        end
        %% %% %% %% %% %% %% %% %% %% %% !!!!!!
    end
    % Component initialization
    methods (Access = private)
        % Create UIFigure and components
        function createComponents(app)
            % Create UIFigure and hide until all components are created
            app.UIFigure = uifigure('Visible', 'off');
            app.UIFigure.Position = [100 100 640 480];
            app.UIFigure.Name = 'MATLAB App';
            % Create NumEditFieldLabel
            app.NumEditFieldLabel = uilabel(app.UIFigure);
            app.NumEditFieldLabel.HorizontalAlignment = 'right';
            app.NumEditFieldLabel.Position = [86 413 31 22];
            app.NumEditFieldLabel.Text = 'Num';
            % Create NumEditField
            app.NumEditField = uieditfield(app.UIFigure, 'numeric');
            app.NumEditField.Position = [132 413 100 22];
            % Create Button
            app.Button = uibutton(app.UIFigure, 'push');
            app.Button.ButtonPushedFcn = createCallbackFcn(app, @ButtonPushed, true);
            app.Button.Position = [132 362 100 22];
            % Show the figure after all components are created
            app.UIFigure.Visible = 'on';
        end
    end
    % App creation and deletion
    methods (Access = public)
        % Construct app
        function app = app8
            % Create UIFigure and components
            createComponents(app)
            % Register the app with App Designer
            registerApp(app, app.UIFigure)
            if nargout == 0
                clear app
            end
        end
        % Code that executes before app deletion
        function delete(app)
            % Delete UIFigure when app is deleted
            delete(app.UIFigure)
        end
    end
end
