| Hi all,
|
| I would like to do this: given a function _f_ in 
two variables and two
| lists l1 and l2, to get the list of all values 
f[a,b] with _a_ in l1 and
| _b_ in l2, with all duplicated values removed. 
How do I do that?
|
| The closest thing that I am able to do is:
|
| 
Table[f[l1[[i]],l2[[j]]],{i,1,Length[l1]},{j,1,Length[l2]}]
|
| but, of course:
|
| 1) what I get is a list of lists;
|
| 2) I eventually get duplicated values.
|
| Best regards,
|
