Yannis, in Mathematica there is no difference between row and column vectors,
but you can use matrices: {{a,b,c}} is a row vector {{a},{b},{c}} is 
a column vector.

You can also use Outer[Times,list1,list2] to get the product of
a column vector list1 and a row vector list2.

But note that the diagonal elements of the outer product of a vector
and itself is just v v (a vector with the elements squared).
