%% Number of Variables in Table %% % Create a table, |T|. LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'}; Age = [38;43;38;40;49]; Height = [71;69;64;67;64]; Weight = [176;163;131;133;119]; BloodPressure = [124 93; 109 77; 125 83; 117 75; 122 80]; T = table(Age,Height,Weight,BloodPressure,'RowNames',LastName) %% % Find the number of variables in table |T|. W = width(T) %% % |T| contains |4| variables; |width| does not count the row names. %% % The variable |BloodPressure| counts as one variable even though it contains % two columns.
