I don't even understand how the comma symbol is being used. Is this an array? Like in javascript? Pi,3-Pi,0 = kv P3,j-P0,j = ku Pi,1-Pi,0 = Pi,3-Pi,2 P1,j-P0,j = P3,j-P2,j

Someone was helping me with figuring out how to make a bezier surface "loop around".

I needed a bezier's surface's left side to match the height of the bezier's edge on the right so that several copies of the bezier surface in a row would be continuous.

These should be written
P(i,3)- P(i,0)= kv
P(3,j)- P(0,j)= ku
P(i,1)- P(i,0)= P(i,3))- P(i,2)
P(1,j)- P(0,j)= P(3,j)- P(2,j).

In other words, those numbers are (integer valued) variables in the function P. Yes, that gives an array.
