How to display a running timer in MATLAB GUI

Hi, I'm trying create an edit text box that displays the time elapsed since pressing the push button that executes my function. I have looked online for information, but I can't seem to decipher from the info I've found exactly what I should be writing in the callback and create function for the edit text box and the callback function for the push button (that also contains the function I have written). It would be really useful for me to have a running timer in my GUI, so any help would be very much appreciated!

Thanks.

function timer_Callback(hObject, eventdata, handles)
% hObject    handle to timer (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hints: get(hObject,'String') returns contents of timer as text
%        str2double(get(hObject,'String')) returns contents of timer as a double
%

% --- Executes during object creation, after setting all properties.
function timer_CreateFcn(hObject, eventdata, handles)
% hObject    handle to timer (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    empty - handles not created until after all CreateFcns called

% Hint: edit controls usually have a white background on Windows.
%       See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor','white');
end

% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

I was trying to do a similar thing except that my timer should start from times gui starts running. This code helped me, http://www.mathworks.com/matlabcentral/fileexchange/12628

how did you do your timer again? I am trying to do the same thing for my GUI but the file in the link does not work for some reason and my MATLAB freezes... Kindly help me

Hey, just an idea, it worked for me.

a = 1:10; % or maybe a higher number 

%Start Button pressed

for i = 1:length(a)
    a(i) = a(:,i);
         uicontrol(f,'Style','text','String',a(i),...
        'Position',[400,300,70,25]);
    pause(1) % produces after 1sec pause a new string in your gui
    
%Stop Button pressed

% make uicontrol visible 'off'
end

I have tried your method but there is an error :

"Error using uicontrol

Cannot set property to a deleted object."
