Well I thought about it, but then I've seen myself stupidly generating
the required X, Y and time dimension indexes wich are strictly regular
and I stopped thinking too much. In my case, the memory access may be
more a problem than the for loops themselves. (I interpolate on the
third dimension of a 200*200*27*24 array).

Thanks,

Fab
