You have two columns, so
squeeze( sum( reshape(YourData, 40, [], 2) ) )

In cases when the total number of elements is not divisible by the size of the smaller groups, and reshape cannot be used, this trick with accumarray may be useful:
V = 1:10 ;
n = 3 ;
rem(numel(V),n) % :-(
ix = floor((0:numel(V)-1)/3) ;
R = accumarray(ix, V ,@sum)
