    %% Cell Array of Character Vectors with Trailing White Space  

%% 
% Create a cell array of character vectors, |A|. 
A = {'dog','cat','fish','horse'};  

%% 
% Create a cell array of character vectors, |B|, where some of the vectors
% have trailing white space.
B = {'dog ','cat','fish ','horse'};  

%% 
% Find the character vectors that are not in the intersection of |A| and
% |B|.
[C,ia,ib] = setxor(A,B) 

%%
% |setxor| treats trailing white space in cell arrays of character vectors
% as distinct characters.
