A variety of ways are covered in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F

If var1 is your variable, when var1 is created or updated:
handles.var1=var1
guidata(hObject,handles)
To call your variable var1 in others functions
var1=handles.var1

Well if you aren't going to read the FAQ, then simply put
global I;
inside every function that needs to use I. I'm also recommending that you don't use I (upper case i) as a variable name. It looks too much like 1 and l (lower case L).
