data = [1 2 3 4 5 6 6.5 10 12 12.5 15 16 17 ;20 20 20 20 20 20 20 13 13 13 20 20 20]';
idx = find(diff(data(:,2))~=0) ;
pos = [[1 ;idx+1] [idx ; length(data)]] ;
iwant = zeros(size(pos,1),1) ;
for i = 1:size(pos,1)
iwant(i) = mean(data(pos(i,1):pos(i,2),1)) ;
end
There would be more elegant procedures.
