This description of what you're trying to do isn't very clear to me. Can you
show a specific example with an 8-by-2 D and a 5-by-2 M? Let's say:
D = [1 2; 2 3; 3 4; 4 5; 2 6; 3 7; 5 8; 17 1]
M = [1 8; 2 9; 5 13; 9 21; 3 2]
What do you expect the result to be for those two matrices, and how did you
arrive at that result? Walk us through the process you'd use to solve that
by hand and we might be able to tell you how to automate that.
