See if the following is what you want In[1]:= vector1 = {a,b,c} Out[1]= {a,b,c} In[2]:= vector2 = {c,d,e} Out[2]= {c,d,e} In[3]:= Outer[Times,vector1,vector2] Out[3]= {{a*c, a*d, a*e}, {b*c, b*d, b*e}, {c^2, c*d, c*e}} In[4]:= MatrixForm[Outer[Times,vector1,vector2]] Note that MatrixForm is such a so-called wrapper that essentially just changes the way things display on the screen. It is not necessary to put the 2nd vector in a 1-column format due to the construction of the Outer[] function.
