how to use keypressFcn to assign the key for push button.?

heisenberg - if you are using GUIDE to create your GUI, then you could assign a WindowKeyPressFcn callback to your figure (GUI) and then, based on the key pressed while the figure has focus, you could call the appropriate button.
Suppose that your GUI/figure is named figure1 and you have one push button (named pushbutton1) that you wish to fire when you press the x key. Your callback to capture key presses could look something like
 function figure1_WindowKeyPressFcn(hObject, eventdata, handles)
 % determine the key that was pressed 
 keyPressed = eventdata.Key;
 if strcmpi(keyPressed,'x')
     % set focus to the button
     uicontrol(handles.pushbutton1);
     % call the callback
     pushbutton1_Callback(handles.pushbutton1,[],handles);
 end
In the above we check for when the x is pressed and then simulate the pressing of the button by calling the appropriate callback. You may not need to set focus to the button using uicontrol but I don't think that it hurts to do this as well.
