Malte,
Try this:
In[1]:= Outer[Times,{a,b,c},{x,y,z}]
Out[1]= {{a x,a y,a z},{b x,b y,b z},{c x,c y,c z}}

Subject: [mg18482] [mg18451] col-vector * row-vector = matrix, how ?
Need to know how to accomplish the following in Mathematica-3.0:
v1 := transpose(<a,b,c>) /* column-vector */
v2 := <x,y,z> /* row-vector */
( ax ay az )
( bx by bz ) = v1 * v2 =: m /* 3x3-matrix */
( cx cy cz )
Does anyone know how to do this in Mathematica ?
Any help is highly appreciated.
Thanks in advance.
Malte.
