How I find rows with same elements but in flipped manner.

Hi, I have a matrix suppose A=[1 2;3 4;2 1; 5 3;4 3]; I need to detect row 1 and 3 as well as row 2 and 5 as unique row. my final matrix should be like A=[1 2;3 4;5 3];

Thank you in Advance

A  = [1 2;3 4;2 1; 5 3;4 3];
As = sort(A, 2);   % [EDITED], was: sortrows(A)
Au = unique(As, 'rows');

Dear Jan, A = [1 2;3 4;2 1; 5 3;4 3]; As = sortrows(A); Au = unique(As, 'rows'); Au=[1 2;2 1;3 4;4 3;5 3]; but my requirement is A=[1 2; 3 4; 5 3];

@Raj: This was a mistake. sort(A, 2) is needed, not sortrows(A). See the [EDITED] code.

Thank you very much Jan. It is working.
