Hi, I'm new in Mathwork, i have this line in matlab gui, but i want to use ''String" instead of "Tag'', The "String" contains many choices (pop up menu), and i don't know what i should change.

comp =num2str(get(findobj('Tag','capacitor'),'Value');

Thanks in advance

What do you want to achieve? It sounds like you want to achieve something different than the required edit in your code.

在 MATLAB Online 中打开

You can retrieve the selections like this

String1=get(handles.popmenu1,'String');
Selection1=String1{get(handles.popmenu1,'Value')};
String2=get(handles.popmenu1,'String');
Selection2=String2{get(handles.popmenu2,'Value')};
if strcmp(Selection1,'foo') && strcmp(Selection2,'bar')
    %do something
else
    %do something else
end

Side note: you should probably move away from GUIDE if you're creating a GUI. It hasn't been great for the past few years, maybe ever. Check out this thread: https://www.mathworks.com/matlabcentral/answers/483657-how-to-create-a-gui.
