Hi,
I have another question that I thought would be simple to to in Mathematica.
I have two vectors A={1,2,3} and B={3,4,5}. How do I multiple them together
to get a 3x3 matrix. A . B gives me a scalar result. Mma seems to always
treat the first one as a row vector and the second as a column vector. I
need it to do the opposite. Treat the first as a column vector and the second
as a row vector. Any ideas?
thanks,
