How can I learn how to read this. I don't even understand how the comma symbol is being used. Is this an array? Like in javascript? Pi,3Pi,0 = kv P3,jP0,j = ku Pi,1Pi,0 = Pi,3Pi,2 P1,jP0,j = P3,jP2,j

Where did you see the equations?

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.

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.
