MATLAB中GUI文本定位按钮,怎么调用代码

要在MATLAB中创建GUI文本和按钮,可以使用GUIDE(图形用户界面设计环境)或手动编写代码。
以下是手动编写代码的步骤:
1. 创建GUI窗口
```matlab
hFig = figure('Position',[300 300 250 150],'MenuBar','none',...
'ToolBar','none','NumberTitle','off','Name','GUI Example');
```
2. 创建文本标签
```matlab
hText = uicontrol('Style','text','Position',[20 100 100 20],'String','Hello World');
```
3. 创建按钮
```matlab
hButton = uicontrol('Style','pushbutton','Position',[100 50 50 30],'String','Click');
```
4. 为按钮添加回调函数
```matlab
set(hButton,'Callback',@buttonCallback);
function buttonCallback(hObject,eventdata)
set(hText,'String','Button clicked!');
end
```
这个例子中,当按钮被点击时,会触发buttonCallback回调函数,将文本标签的字符串修改为“Button clicked!”。
最后,使用`guidata`将所有句柄存储在结构体中,以便在回调函数中使用。
```matlab
handles.hFig = hFig;
handles.hText = hText;
handles.hButton = hButton;
guidata(hFig,handles);
```
这样,你就可以在回调函数中使用`handles`结构体来访问句柄了。
