I have a Nx2 matrix with identical pairs. Something like this:

b_data = [ 1 2; 3 4; 7 10; 2 1; 10 7; 11 12];

i consider 1 2, 2 1 as identical

I need to make this

b_data = [1 2; 3 4;7 10; 11 12];

Is there any command for doing so?

use something like

unique(sort([1 2; 2 1; 3 5],2),'rows')

Ah, sorry, I must have read it too quickly. Have an upvote as an apology.
