Hello all,
I have 4 matrices with 3 columns each (different number of rows though). I
want to find a function that returns all possible 3-place vectors
corresponding to the sum by columns of picking one row from matrix 1, one
from matrix 2, one from matrix 3, and one from matrix 4. So basically,
Homework? We don't do homework here.

I expect the answer to involve manipulating indices. But why do you need to do
this? This looks suspiciously like homework, and there is a no-homework policy
on this list (see the Posting Guide).
