You have two columns, so

squeeze( sum( reshape(YourData, 40, [], 2) ) )

It would be much simpler if you followed the suggestions IA has given, but since each subplot seems to be a stem of some variable, the answer would seem to be that you would consult

doc mean
doc std

and apply them to the various variables which you in turn plotted. That seems so patently obvious however that surely there's more to the question than that????
