    %% Preserve Legacy Behavior of setdiff  
% Use the |'legacy'| flag to preserve the behavior of |setdiff| from R2012b
% and prior releases in your code.   

%% 
% Find the difference of |A| and |B| with the current behavior. 
A = [3 6 2 1 5 1 1]; 
B = [2 4 6];
[C1,ia1] = setdiff(A,B)  

%% 
% Find the difference of |A| and |B|, and preserve the legacy behavior. 
[C2,ia2] = setdiff(A,B,'legacy')
