Thanks! yes, that's the ticket.

In testing out your solution, I noticed I described my problem wrongly. 

Apologies to anyone I confused.

So a clarification for anyone trying to follow this:

The index for y should have been y[i+j-1]

Gabor's solution is correct for the question as asked, and it works just
fine when I apply it to what I *should* have asked:

z <- x * y[row(x) + col(x) -1]
