Hello everyone, I have created a callback function of a button in GUI, now i want to record the elapsed time from the point of i click the button to the point a certain condition is met and save it in a cell(T0)in workspace. I added 'tic' in the callback function and 'toc' after the condition is met.
function pushbutton1_Callback(hObject, eventdata, handles)
tic;
if...
T0{t}=toc;
...
end
assignin('base','T0',T0)
The problem is that the whole process runs smoothly and no error occurred but there was no T0 in workspace. Anyone could help or give me some suggestions? Thanks in advance.

W - put a break point at the line
assignin('base','T0',T0)
and re-run your code. When you press pushbutton1, the debugger will pause at this line. Look at T0 - has it been initialized (i.e. has the condition been met)? Then step over this line to see what happens. You may want to evaluate this line in the command window just to see what happens.

I seriously doubt there is any need to save it to the base workspace. I never save anything to the base workspace - ever. There is just no need to.
To save it or share it with other functions, see the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F
