%% Difference of Two Tables and Indices to Different Rows %% % Define a table, |A|, of gender, age, and height for five people. A = table(['M';'M';'F';'M';'F'],[27;52;31;46;35],[74;68;64;61;64],... 'VariableNames',{'Gender' 'Age' 'Height'},... 'RowNames',{'Ted' 'Fred' 'Betty' 'Bob' 'Judy'}) %% % Define a table, |B|, with the same variables as |A|. B = table(['F';'M';'F';'F'],[64;68;62;58],[31;47;35;23],... 'VariableNames',{'Gender' 'Height' 'Age'},... 'RowNames',{'Meg' 'Joe' 'Beth' 'Amy'}) %% % Find the rows in |A| that are not in |B|, as well as the index vector % |ia|, such that |C = A(ia,:)|. [C,ia] = setdiff(A,B) %% % The rows of |C| are in sorted order first by |Gender| and next by |Age|.
