How can I delete the repeated values and keep just a row of each one?

I have this matrix

[3 11 43;

3 17 41;

3 41 17;

3 43 11;

11 3 43;

11 43 3;

17 3 41;

17 41 3;

41 3 17;

41 17 3;

43 3 11;

43 11 3 ]

The result should be something like this [ 3 11 43; 3 17 41 ]

OBS. I tried unique() and it didn't work as I want.

DS - you could try

 unique(sort(A,2), 'rows')

where A is the matrix that you have defined above. This could be inefficient though especially as your A gets larger. With this code, we sort all the columns for each row of A and then calll unique with rows so that each row is treated as a "single entity". See unique values in array for details.

A = unique(sort(a,2),'rows') % where a is your matrix
