Hello, I have the following to do: Given In[1]:= A={1,2,3}; B={{a,b},{c,d},{r,s}}; And a Function f, I like to have Out[2] = {f[1,a],f[1,b]}+{f[2,c],f[2,d]}+{f[3,r],f[3,s]} The trial In[8]:=A={1,2,3}; B={{a,b},{c,d,e},{r,s}}; In[9]:= Inner[f,A,B] Out[9]= f[1,{a,b}]+f[2,{c,d,e}]+f[3,{r,s}] looks promising, but if the Lists in B have the same length, "Inner" makes something different: In[15]:= A={1,2,3}; B={{a,b},{c,d},{r,s}}; Inner[f,A,B] Out[16]= {f[1,a]+f[2,c]+f[3,r],f[1,b]+f[2,d]+f[3,s]} So for now I have an ugly Table-Construction doing the job, but I can't imagine there is no elegant and clear solution for this ... any suggestions? Greetings, Detlef
