I understand that one of the unique point of Mathematica is that you don't
have to be conscious about whether a vector is a "row" or a "column" vector.
However, I think there is a case in which you have to specify whether you
want Mathematica to recognize a vector as a row vector or a column vector.
Let me explain my case.
I want to define "a" as a column vector (3x1 matrix) and "b" as a row vector
I expect the product
as a 3x3 matrix, but the answer Mathematica gives is a scalar product "32".
Please give me an advice to get the 3x3 matrix as a product.
