matlab: remove duplicate values

Question

I\'m fairly new to programming in general and MATLAB and I\'m having some problems with removing values from matrix.

I have matrix tmp2 with values:

Answer 1

I saw the solution with unique, and wanted to give a solution with loops. You can take a look to see which one is faster :D! The loop could probably be ameliorated...

clear
tmp = [0.6000   20.4000
        0.7000   20.4000
        0.8000   20.4000
        0.9000   20.4000
        1.0000   20.4000
        1.0000   19.1000
        1.1000   19.1000
        1.2000   19.1000
        1.3000   19.1000
        1.4000   19.1000];

ltmp = length(tmp);
jj = 1;
for ii = 1 : ltmp
    if ii > 1
        if tmp(ii, 1) == tmp(ii - 1, 1)
            continue
        end
    end
    if ii < ltmp
        if tmp(ii, 1) == tmp(ii + 1, 1)
            tmp2(jj,1) = tmp(ii, 1);
            tmp2(jj,2) = min(tmp(ii, 2),tmp(ii + 1, 2));
        else
            tmp2(jj, 1) = tmp(ii, 1);
            tmp2(jj, 2) = tmp(ii, 2);
        end
    else
            tmp2(jj, 1) = tmp(ii, 1);
            tmp2(jj, 2) = tmp(ii, 2);
    end
    jj = jj + 1;
end
