A slight error in Equation 6
Hunter Moseley (2012-10-26 17:22) University of Louisville
There is a slight error in Equation 6 in the two summation terms.
The summation should be for y = 0; y ≤ j and x = 0; x ≤ i with the following condition (y ≠ j or x ≠ i) that must be satisfied as well. It is easier to describe this summation with a single summation term which includes the conditional, which I have tried to represent below given the limitations of this editor:
y ≤ j; x ≤ i; y ≠ j or x ≠ i
∑
y = 0; x = 0
