Thanks Greg,
That exactly what I want for this case. But in a case where the
function is not as simple as the MEAN function. Let's say that I want
to compute the curvature of the DEM, with my own function CURV(H), is
it possible to make it as simple as for the mean ?

curvature=curv(H)

...hum maybe my question is stupid ! it depends on the way I write my
function ?

Thanks again,
Cheers
Laurent
