MATLAB程序代码使用appdesigner设计界面，通过输入温度的变化触发lamp控件颜色的改变，并显示figure界面

好的，这里是MATLAB程序代码，代码中使用了appdesigner设计界面，通过输入温度的变化触发lamp控件颜色的改变，并显示figure界面：

classdef TemperatureControlApp < matlab.apps.AppBase

    % Properties that correspond to app components
    properties (Access = public)
        UIFigure        matlab.ui.Figure
        TemperatureEditLabel    matlab.ui.control.Label
        TemperatureEdit matlab.ui.control.NumericEditField
        Lamp            matlab.ui.control.Lamp
    end

    % Callbacks that handle component events
    methods (Access = private)

        % Value changed function: TemperatureEdit
        function TemperatureEditValueChanged(app, event)
            value = app.TemperatureEdit.Value;
            if value >= 30
                app.Lamp.Color = 'red';
            elseif value >= 20
                app.Lamp.Color = 'yellow';
            else
                app.Lamp.Color = 'green';
            end
        end

        % Close request function: UIFigure
        function UIFigureCloseRequest(app, event)
            delete(app);
        end
    end

    % App initialization and construction
    methods (Access = private)

        % Create UIFigure and components
        function createComponents(app)

            % Create UIFigure
            app.UIFigure = uifigure;
            app.UIFigure.Name = 'Temperature Control App';
            app.UIFigure.CloseRequestFcn = createCallbackFcn(app, @UIFigureCloseRequest);

            % Create TemperatureEditLabel
            app.TemperatureEditLabel = uilabel(app.UIFigure);
            app.TemperatureEditLabel.HorizontalAlignment = 'right';
            app.TemperatureEditLabel.Position = [266 354 71 22];
            app.TemperatureEditLabel.Text = 'Temperature';

            % Create TemperatureEdit
            app.TemperatureEdit = uieditfield(app.UIFigure, 'numeric');
            app.TemperatureEdit.ValueChangedFcn = createCallbackFcn(app, @TemperatureEditValueChanged);
            app.TemperatureEdit.Position = [353 354 100 22];

            % Create Lamp
            app.Lamp = uilamp(app.UIFigure);
            app.Lamp.Position = [296 230 100 100];
        end
    end

    % App creation and deletion
    methods (Access = public)

        % Construct app
        function app = TemperatureControlApp

            % Create UIFigure and components
            createComponents(app)

            % Show the figure after all components are created
            app.UIFigure.Visible = 'on';
        end
    end
end

该代码实现了一个温度控制的应用程序，界面中包含一个TemperatureEdit控件，用于输入温度值，一个Lamp控件用于显示温度状态。当输入的温度值大于等于30时，Lamp的颜色为红色；当输入的温度值大于等于20时，Lamp的颜色为黄色；当输入的温度值小于20时，Lamp的颜色为绿色。在TemperatureEdit控件的ValueChangedFcn回调函数中实现了Lamp控件颜色的改变。该代码还添加了UIFigure界面，可通过运行该代码在MATLAB中显示出应用程序界面。
