Hierachical State transition with matlab OOP !!!!!!!!!!!!!!!!!

Hello,

I want to implement a state machine in MATLAB OOP. But I'm andicaped, by the implementation of state transition. In my implementation, the root state define event which are handle in distincts states. (n) denote notification action and (l) listening. State which do not implement notify action for a event inherit callback for this event from root state class. to help you figure out what I mean, assume :

classdef stateRoot 
events
event1
event2
event3
event4
event5
event6
end
end %end stateRoot

classdef state1 < stateRoot

events
events1(n)

event2(l)
end
end % end state1

classdef state2 < stateRoot

events
event3(n)
event4(l)
end
end % %end state2

classdef state3 < stateRoot

events
event4(l)
event5(l)
end
end % end stat3

classdef machine < state1&state2&state3

methods
%
%
end
end %end machine

The machine change state from state1 to state3 and then comback to state1. So now my question : How can I implement the transition from one state to another? Ist any way achieving this other than evently triggering? cause I've already got to many evnts in my code so it become slowly confusing.

Thanks for your help
