Need help to delete a variable in matlab
显示 更早的评论
I have created a Matlab GUI with 2 buttons, connect and disconnect, which connect and disconnects a arduino, but i have an error with my disconnect button, this is my code:
function disconnect_Callback(hObject, eventdata, handles)
% hObject handle to disconnect (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
delete(handles.a);
msgbox('Arduino successfully Disonnected','Disconnected');
Whenever I press the disconnect button, i get the following error: "Cannot access method 'delete' in class 'arduino'."
Please help

What is the contents of handles.a?

And does this work:
a = arduino(port);
pause(1);
delete(a)

Maybe try
rmfield(handles, 'a');
If that doesn't work, then I would not recommend attaching the arduino object to the handles structure. I'd just keep it separate. In fact, I'd recommend this anyway.
