matlabapp单选按钮组

在MATLAB App Designer中创建单选按钮组，你可以使用`ButtonGroup`和`RadioButton`组件。以下是一个简单的例子，展示如何在MATLAB App Designer中创建单选按钮组：

1. 打开MATLAB App Designer并创建一个新的App。

2. 在App Designer界面的左侧组件库中，找到`ButtonGroup`和`RadioButton`组件。

3. 将`ButtonGroup`组件拖放到App Designer的UI界面中。

4. 在属性编辑器中，为`ButtonGroup`设置适当的属性，如位置和大小。

5. 右键点击`ButtonGroup`组件，选择"Add RadioButton"，添加所需数量的单选按钮。

6. 对每个单选按钮进行属性设置，例如设置文本标签和回调函数。

7. 在每个单选按钮的回调函数中，编写相应的代码以响应选择事件。

8. 运行App，你将看到一个包含单选按钮组的界面。

下面是一个示例代码，演示如何在App Designer中创建并使用单选按钮组：

classdef MyApp < matlab.apps.AppBase

    % Properties
    properties (Access = private)
        UIFigure           matlab.ui.Figure
        ButtonGroup        matlab.ui.container.ButtonGroup
        RadioButton1       matlab.ui.control.RadioButton
        RadioButton2       matlab.ui.control.RadioButton
        RadioButton3       matlab.ui.control.RadioButton
    end

    % Methods
    methods (Access = private)

        % Value changed function for RadioButton1
        function RadioButton1ValueChanged(app, event)
            disp('RadioButton1 selected');
        end

        % Value changed function for RadioButton2
        function RadioButton2ValueChanged(app, event)
            disp('RadioButton2 selected');
        end

        % Value changed function for RadioButton3
        function RadioButton3ValueChanged(app, event)
            disp('RadioButton3 selected');
        end

        % Close request function
        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 = 'My App';
            app.UIFigure.CloseRequestFcn = createCallbackFcn(app, @UIFigureCloseRequest);

            % Create ButtonGroup
            app.ButtonGroup = uibuttongroup(app.UIFigure);
            app.ButtonGroup.Title = 'Select an option';
            app.ButtonGroup.Position = [100 200 200 100];

            % Create RadioButton1
            app.RadioButton1 = uiradiobutton(app.ButtonGroup);
            app.RadioButton1.Text = 'Option 1';
            app.RadioButton1.Position = [11 50 100 22];
            app.RadioButton1.ValueChangedFcn = createCallbackFcn(app, @RadioButton1ValueChanged);
            
            % Create RadioButton2
            app.RadioButton2 = uiradiobutton(app.ButtonGroup);
            app.RadioButton2.Text = 'Option 2';
            app.RadioButton2.Position = [11 28 100 22];
            app.RadioButton2.ValueChangedFcn = createCallbackFcn(app, @RadioButton2ValueChanged);

            % Create RadioButton3
            app.RadioButton3 = uiradiobutton(app.ButtonGroup);
            app.RadioButton3.Text = 'Option 3';
            app.RadioButton3.Position = [11 6 100 22];
            app.RadioButton3.ValueChangedFcn = createCallbackFcn(app, @RadioButton3ValueChanged);

        end
    end

    % App creation and deletion
    methods (Access = public)

        % Construct app
        function app = MyApp

            % Create and configure components
            createComponents(app)

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

    end

    % App lifecycle management
    methods (Access = public)

        % Run the app
        function run(app)
            if ~isdeployed
                % Set the UIFigure visible and handle visibility changes
                set(app.UIFigure, 'HandleVisibility', 'on');
            end
        end

        % Delete the app
        function delete(app)
            % Delete UIFigure when app is deleted
            delete(app.UIFigure);
        end
    end

    % App startup and teardown
    methods (Access = public, Static)

        % Start the app
        function startApp
            app = MyApp;

            % Allow app to run outside of App Designer environment
            if ~isdeployed
                run(app);
            end
        end
    end

end

在上述代码中，我们创建了一个名为`MyApp`的App类，并添加了`ButtonGroup`和三个`RadioButton`组件。我们分别为每个`RadioButton`定义了相应的值改变回调函数。在这些回调函数中，我们使用`disp`函数打印所选的选项。

通过运行`MyApp.startApp`来启动App，然后你将看到一个带有单选按钮组的界面。每次选择单选按钮时，相应的回调函数将被触发，并显示相应的消息。

你可以根据需要自定义单选按钮组的样式，以及回调函数中的具体操作。
