Help is required on how to tacle the following error messages:

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

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

4. Error in ==> @(hObject,eventdata)QPR('pushbuttoncompute_Callback',hObject,eventdata,guidata(hObject))

5. ??? Error while evaluating uicontrol Callback

Something in the routine pushbuttoncompute_Callback references a variable named "cou", but that variable is undefined.

We do not have enough information to provide guesses as to what "cou" should be or why it is undefined.
