Well, from my limited knowledge correlation just shows if there is linearity in 
two data sets, and I can't comprehend how can correlation be used in 
determining sequnced data. I read commented xcorr.m file, but can't see any 
pointers to my problem, nor understand what lag is

Of course, but as I can't present all points I thought just to pick in the 
graph :)

Yeah, there is some time ahead
