Hi,
Is there a easy way to remove rows with same elements in a 2D matrix. For example, i have a matrix A = [1 2; 2 3; 1 2; 3 4; 2 1]
The 'unique' command doesn't help as it will give you the output [1 2; 2 3; 3 4; 2 1]. It's not deleting the last row [2 1] which has the same element as first row.
But i want the output like this [1 2; 2 3; 3 4].
Thanks,
Asad

[~,i] = unique(sort(A,2),'first','rows');
out = A(i,:);

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