%% Compare Values in Categorical Array
% Create an ordinal categorical array.

A = categorical({'large' 'medium' 'small'; 'medium' ...
'small' 'large'},{'small' 'medium' 'large'},'Ordinal',1)

% The array has three categories: 'small', 'medium', and 'large'.
%
% Find all values greater than or equal to the category 'medium'.

A >= 'medium'

% A value of logical 1 (true) indicates a value greater than or equal to the category 'medium'.
%
% Compare the rows of A.

A(1,:) >= A(2,:)

% The function returns logical 1 (true) where the first row has a category value greater than or equal to the second row.
