a=[ 0 0 10 150 150 0 125 150 0 10 125 150
0 0 80 0 0 70 80 55 70 80 80 55]
out = unique(a.','rows')'
add
a0 = unique(a.','rows');
t = ismember(a0(:,1),a0(size(a0,1),1));
a0(t,2) = sort(a0(t,2),'descend');
out = a0.';
Please read about functions unique, size, ismember, sort.

That's not a very useful statement, I'm afraid. You could always google, as all the documentation is online.
