 out=[0 1;1 3;2 5;3 5; 7 2; 8 1;9 1;11 4];
for i=1:8
if out(i,2)==max(out(:,2))
val=out(i,1)
end
 end

The output i need is 2 and 3, but in my code the variable 'val' stores only 3. I want to store 2 and 3 in the vector 'val. Any one help me?

out=[0 1;1 3;2 5;3 5; 7 2; 8 1;9 1;11 4];
k = 0;
for i=1:8
    if out(i,2)==max(out(:,2))
        k = k + 1;
        val(k)=out(i,1);
    end
end

val = out(out(:,2)==max(out(:,2)),1);
