%% Test for Category with No Corresponding Data %% % Create a categorical array, |A|. A = categorical({'plane' 'car' 'train' 'car' 'plane'},... {'boat' 'car' 'plane' 'train'}) %% % |A| is a 1-by-5 categorical array. %% % Test to see if |boat| is a category in |A|. tf = iscategory(A,'boat') %% % |iscategory| returns true, even though |A| does not contain any values % from the category |boat|.
