Another loop avoidance question.
Hi
I want to sum over one of the dimensions of a n x k1 x k2 array in
which each column is the product of the corresponding columns from two
matrices with dimensions n x k1 and n x k2. I can see two approaches:
a loop on k1 and a loop on k2. But I cannot figure a solution that
avoids the loop? Is it possible? (I don't refer to apply or lapply etc
either as they are just hidden loops so,
