Hi All,
(I have a degree in math, but I am too embarassed to ask my colleagues, so here goes:)
I would like to get a vector normal (orthogonal) to a plane formed by two other vectors. In matlab I do this:
v1 = [.4, .6, .8]; v2 = [.9, .7, .2]; nn = cross(v1,v2) (gives ~[-.48, .65, -.24]
if I do R> cross(v1, v2), I get .94. Huh?
Thanks for all your help, again.
W
