Hi Stephen

Yes, just use a (1, n) or (n, 1) matrix as appropriate and do matrix
operations instead of vector ops. The results will be correct as long as you
make sure you have a correctly dimensioned matrix in place of your vector
(i.e one that matches your vectors size and orientation). After all a matrix
is just a collection of vectors ;-)

cheers,
Scott
