This is because some administration is required foraccessing rows for a variety of types of matrices. To reduce theadministration a special multiply routine is used for rectangularmatrices in place of the generic one. Where operations can be donewithout reference to the individual rows (such as adding matrices of thesame type) appropriate routines are used.<P>When you are using small matrices (say smaller than 10 x 10) you mayfind it faster to use rectangular matrices rather than thetriangular or symmetric ones.</BODY></HTML>⌨️ 快捷键说明
