Hi, I'm not native English, what is the name the following product. Let a n-column vector and b m-row vector, than c = a × b resultes a n-by-m-matrix:
c_ij = a_i * b_j.

i don't know if there's a name for this but what you've defined is simply this
What does ba mean?
b and a are vector, and n <>= m.
This product is very usefull sometimes,for example:
the matrix of the tranformation r --> a(br) is
T = a × b
where a, b, r is spatial vector, and br is scalar product
