1 2 4
7 9 6
1 2 4

and i want delete the same rows. My new matrix should be

4 5 6
7 9 6

how can I do this?

Solution

  • I think this script may do what you want:

    B= A;
position = 1;
condition = true;
bSize = size(B,1);
while (position < bSize)
    [~,~,ic] = unique(B,'rows');
    changes = find(ic(position:end,:)== ic(position));
    if (length(changes)>1)
        B(changes+position-1,:)= [];
        bSize = size(B,1);
    else
        position = position+1;
    end
end
disp(B)
