I am looking for efficient ways to code neighbourhood functions. For
example a neighbourhod add for an element in an array will simply be the sum
of the neighbours:
1 0 2
3 x 3 , then x becomes 7 (first order neighbour), 11 (2nd order) etc.
1 1 0
I would be interested in efficient ways of doing this for a whole array,
something like a_nsum = neighbour_sum(a, order=1), where each element in
a_nsum is the sum of the corresponding element in a.
There must be some work done on neighbourhood functions for arrays, so I
would be grateful for some pointers.
Thanks,
Robert Denham
