‘What I use for xq value?’
You don’t.
Instead, you convert them to a timetable (create your matrix as a table, then use use table2timetable to convert it to a timetable), then use the retime function to get the annual mean values. See the retime documentation sections on newTimeStep and method for an explanation of how to use those arguments.
