%% Preserve Legacy Behavior of intersect % Use the |'legacy'| flag to preserve the behavior of |intersect| from % R2012b and prior releases in your code. %% % Find the intersection of |A| and |B| with the current behavior. A = [7 1 7 7 4]; B = [7 0 4 4 0]; [C1,ia1,ib1] = intersect(A,B) %% % Find the unique elements of |A| and preserve the legacy behavior. [C2,ia2,ib2] = intersect(A,B,'legacy')
