find matching rows in matrices
I want to find which rows in two matrices that are matching. If I for example have A = 1 2 4 5 9 7 1 2 6 5 and B = 2 5 1 2 9 2 1 2 I would like a result like index_A=[1 4] index_B=[2 4]. Any idea how to solve this?

Use the 2nd and 3rd returned arguments in 'intersect':
[~,index_A,index_B] = intersect(A,B,'rows');
