I have an array:

DOM =
     [1     1     1    0;
   1     1     0;
   1     0     0;
   1     0     0;
   0     1     0;
   0     1     0]

I need to eliminate the dublicate rows but without changing the order of the rows in Dom. I s there a MATLAB function for doing so or do I have to write a loop?

I tried

D=unique(DOM, 'rows');

D =

0 1 0 0

1 0 1 0

1 1 1 0

Thanks
