%% Left Outer-Join Operation of Tables and Indices to Values %% % Create a table, |A|. A = table({'a' 'b' 'c' 'e' 'h'}',[1 2 3 11 17]',... 'VariableNames',{'Key1' 'Var1'}) %% % Create a table, |B|, with common values in the variable |Key1| between % tables |A| and |B|, but also containing rows with values of |Key1| not % present in |A|. B = table({'a','b','d','e'}',[4;5;6;7],... 'VariableNames',{'Key1' 'Var2'}) %% % Use the |outerjoin| function to create a new table, |C|, with data from % tables |A| and |B|. Ignore rows in |B| whose key values do not match any % rows in |A|. % % Also, return index vectors, |ia| and |ib| indicating the correspondence % between rows in |C| and rows in |A| and |B| respectively. [C,ia,ib] = outerjoin(A,B,'Type','left') %% % All values of |ia| are nonzero indicating that all rows in |C| have corresponding % rows in |A|.
