vectors multiplication  dennis  04232004 Hello,
There is no problem writing [[1,2,3][4,5,6]*[[7,8][9,10][11,12]]
But if the two matrix are two vectors ((n*1) and (1*n)) the multiplication insn't possible. [ERROR: invalid dimension!!!] Re: vectors multiplication  Tom Sherman  04232004 Dennis, Go to the math menu, select the vectors menu, and then select DOT. If you are in RPN mode, you will want to enter your vectors before doing this; if you are in algebraic mode, the vectors are entered after selecting DOT. If you have a manual, see page 85. I hope it works for you.
Tom
