For more information, see “Inputting and Editing Matrices” (page 2-42)and “Matrix Cell Operations” (page 2-44). Note, however, that vector calculations differ frommatrix calculations as described below.• On the vector memory element input screen, there is no 1(ROW-OP) in the function menu.• For vector editing, the dimension always limited to m rows × 1 column or 1 row × n columns.k Vector Calculations [OPTN]-[MAT/VCT]Use the vector command menu to perform vector calculations.u To display vector commands1.

Also, a cross product’s dimensions mustbe 1 × 2, 1 × 3, 2 × 1, or 3 × 1.• Vector calculations are performed independently for each element, so it may take some timebefore calculations results are displayed.
