双击弹出式菜单，会弹出一个小窗口。在窗口中找到string属性，可以根据需要进行修改。本例中，将属性值改为"x, sin(x), cos(x)"，以绘制这三个函数的图像。接着，打开GUI的m文件，找到函数"popupmenu1_Callback(hObject, eventdata, handles)"。在该函数的代码中，添加如下所示的代码片段。修改完...

打开这个POPUPMENU的Callback函数，在下面写这样的代码：val=get(handles.popupmenu1,'value'); %假定这个下拉菜单的TAG是popupmenu1 switch val case '1' %假定你把'打开图片'放在下拉菜单的最上面 [filename fileadress]=uigetfile('*jpg');case '2' %下面还有几个选项 ...end 这样...
1 step1 打开GUI首先在Matlab软件中打开需要新加弹出式菜单控件的GUI；如果没有GUI，则按照引导首先新建空白gui 2 step2 选中弹出式菜单控件进入空白gui后，首先在控件列表中选中弹出式菜单控件 3 step3 放置控件在画布区放置弹出式菜单控件，并根据设计需要调整控件的大小 4 step4 添加下拉菜单双击控件弹出属性设置，...

5 5、修改之后，打开GUI的m文件，找到function popupmenu1_Callback(hObject, eventdata, handles)在它下面添加如图所示代码 6 6、代码添加后保存，然后退出m文件，点击GUI界面工具栏最后一个绿色三角形，也就是运行按钮，将会出现如图界面，选择想要绘制的函数，点击后将会在坐标轴绘制图像 ...
