2 DD(I,J) = B+B+A*REL
3 PXX = X(I+1,J)-2.*X(I,J)+X(I-1,J)
4 QXX = Y(I+1,J)-2.*Y(I,J)+Y(I-1,J)
5 PYY = X(I,J+1)-2.*X(I,J)+X(I,J-1)
6 QYY = Y(I,J+1)-2.*Y(I,J)+Y(I,J-1)
7 PXY = X(I+1,J+1)-X(I+1,J-1)-X(I-1,J+1)+X(I-1,J-1)
8 QXY = Y(I+1,J+1)-Y(I+1,J-1)-Y(I-1,J+1)+Y(I-1,J-1)
9 RX(I,J) = A*PXX+B*PYY-C*PXY
