Do you mean something like this: In[37]:= (m = {a, b, c}*v /. v -> {x, y, z}) // MatrixForm Out[37]//MatrixForm= a x a y a z b x b y b z c x c y c z ? -- Andrzej Kozlowski Toyama International University JAPAN http://sigma.tuins.ac.jp http://eri2.tuins.ac.jp ---------- >From: malte.lance at gmx.net (Malte Lance) To: mathgroup at smc.vnet.net >To: mathgroup at smc.vnet.net >Subject: [mg18513] [mg18451] col-vector * row-vector = matrix, how ? >Date: Wed, Jul 7, 1999, 1:11 PM > > 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. > > -- > Malte Lance. > --- composed with knews
