This is a very FAQ. So see the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F

MATLAB: Question about the function of callback

Function handles cannot be combined in an array due to the konfusion of the indexing and the input arguments. But you can create a cell of function handles:

C = {@sin, @cos, @tan};
for i = 1:3
   feval(C{i}, pi)
   % In modern Matlab versions also directly:
   % C{i}(pi)
end

Similar works for pushbutton_callback{k}.

MATLAB: How to execute checkbox callback by using pushbutton callback

h = HandleOfOtherControl;
cb = get(h, 'Callback');  %this retrieves the callback
cb{1}(h, [], cb{2:end});  %this invokes the callback

Warning to other readers: this sequence will not work for callbacks constructed by GUIDE, as those use are strings instead of cell arrays of that contain the function handle. Fortunately Karthick KJ does not appear to be using GUIDE (or at least has not mentioned using GUIDE in any posting.)
