%% Test for Categories
% Create an ordinal categorical array, A.

A = categorical({'shirt' 'pants'; 'pants' 'hat'; 'shirt' 'pants'})

% A is a 3-by-2 categorical array.
%
% Test if the articles of clothing, shirt, pants, socks, and shoes, are categories of A.

catnames = {'shirt' 'pants' 'socks' 'shoes'};
tf = iscategory(A,catnames)

% shirt and pants are categories of A, but socks and shoes are not.
% iscategory does not tell us anything about the category, hat, which we did not include in catnames.
