Using John's drawing above, in my implementation:

23 25

a <- (2a + d + b + ---- e + ---- c)/6

24 24

where the numerical factors come from the radial index.

This form follows directly from the Laplacian. I also generate a

row (in my case) with radial coordinates. My cells on axis have

a different formula; the surrounding cells are unweighted for

these cells.

This differs from the formula posted by JohnM this morning.

His was:

a <- [(b+c+d+e)+(c-e)/(2*r)]/4
