%% Cell Array of Character Vectors with Trailing White Space
% Create a cell array of character vectors, A, where some of the vectors have trailing white space.

A = {'dog','cat','fish','horse','dog ','fish '};

%
% Find the unique character vectors contained in A.

C = unique(A)

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