Here:

http://docs.scipy.org/doc/numpy/reference/c-api.array.html#functions

You can find some examples in the multiarray_tests.c in numpy/core
(which test "stacked iterators"), as well as in scipy.signal (the
nd-correlate function uses the neighborhood iterator).

Note that optimizations such as used in VTK to separate the zones
where boundaries handling is needed from the ones without is not
implemented yet.

cheers,

David
