Give an example of what your inputs look like otherwise it is impossible to answer. There aren't any prizes for the shortest "question" statement on the forum!

load yourdata.mat
[ym,~,c] = unique(a(:,1:2),'rows');
s = size(a)-[0,3];
ii = repmat(c,s(2),1);
jj = repmat(1:s(2),s(1),1);
out = [ym,accumarray([ii,jj(:)],reshape(a(:,4:end),[],1),[],@mean)];
