Errors when I close GUI

I created a togglebutton in GUI and used while get(hObject,'Value') to get into the loop.

While the togglebutton is pressed the loop is running and if I want to close the gui window while the loop is running I get following errors:

??? Error using ==> plot Data must be a single matrix Y or a list of pairs X,Y

Error in ==> Voice_measure_gui>Start_Callback at 115 plot(handles.time_domain,time,data)

Error in ==> gui_mainfcn at 96 feval(varargin{:});

Error in ==> Voice_measure_gui at 42 gui_mainfcn(gui_State, varargin{:});

Error in ==> @(hObject,eventdata)Voice_measure_gui('Start_Callback',hObject,eventdata,guidata(hObject))

??? Error while evaluating uicontrol Callback

The intention of the code is to sample voice speech and to plot its time domain and freq. domain in real time.

Please advice

 Does delete() help you, if not try to use break

Hello Luffy,

I tried delete, the effect is the same. break mostly used in 'while'or 'for' loops. When I hit close figure, how to know that I pressed the close figure button?

hello Jan,

can you suggest a small code that clarify your answer (I'm not so strong in GUI coding).

Thanks,

So you have to stop the loop, before the figure is closed. The CloseRequestFcn is the best place for code to cleanup.
