%% Symmetric Difference of Rows in Two Matrices
% Define two matrices with rows in common.

A = [7 8 9; 7 7 1; 7 7 1; 1 2 3; 4 5 6];
B = [1 2 3; 4 5 6; 7 7 2];

%
% Find the rows of A and B that are not in their intersection as well as the index vectors ia and ib.

[C,ia,ib] = setxor(A,B,'rows')

% C is a sorted combination of the rows of A(ia,:) and B(ib,:).
