%% Add Categories and Specify Category to Precede %% % Create an ordinal categorical array. A = categorical({'medium' 'large'; 'small' 'xlarge'; 'large' 'medium'},... {'small' 'medium' 'large' 'xlarge'},'Ordinal',true) %% % Display the categories of |A|. categories(A) %% % Since |A| is ordinal, the categories have the mathematical ordering |small % < medium < large < xlarge|. %% % Add the category |xsmall| before |small|. B = addcats(A,'xsmall','Before','small') %% % |B| contains the same values as |A|. %% % Display the categories of |B|. categories(B) %% % The categories have the mathematical ordering |xsmall < small < medium % < large < xlarge|.
