%% Create and Label Ordinal Arrays % Copyright 2015 The MathWorks, Inc. %% % Create an ordinal array from integer data, providing explicit labels. quality = ordinal([1 2 3 3 2 1 2 1 3],... {'low' 'medium' 'high'}) %% % Show that the first element is less than the second element (low is less % than medium). quality(1) < quality(2) %% % Create an ordinal array by binning values between 0 and 1 into thirds % with labels |'small'|, |'medium'|, and |'large'|. X = rand(5,2) A = ordinal(X,{'small' 'medium' 'large'},[],[0 1/3 2/3 1])
