Silly me, of course. Math class was just too many years ago.

Hello
The + sighs between cross terms should be replaced by - signs as follows:
i ( a_2b_3 - a_3b_2 )
+ j ( a_3b_1 - a_1b_3 )
+ k (a_1b_2 - a_2b_1 )

I don't know if this is correct, but I took a quick attempt at making a cross
product. I am using the dataset can.exo. In the calculator, I am trying to
create the cross of the DISP and ACCL vectors. Here is the formula:
iHat*(DISPL_Y*VEL_Z+DISPL_Z*VEL_Y)+jHat*(DISPL_X*VEL_Z+DISPL_Z*VEL_X)+kHat*(DISPL_X*VEL_Y+DISPL_Y*VEL_X)

I am trying to do a vector product with the Calculator, but this seems to fail
"Error deciding between ambiguous operators".
Is there a way to do vector products ? Or is this something that needs to be
implemented ?
