Thanks to Chris for the inspired information, and
to Ed for suggestions about PDL::Transform that I need to review.
For now I have a first awful but seems to be a functional version
$field is ndarray with doubles [2,$N,$N]
$x are the index for $M < $N that I want to decimate
my @field_int_f=();
m
If M and N are integers and N%M == 0 then you could use indexing and
dimension "tricks" to collect the values for the new pixels to the first dim
and then apply your preferred interpolation/smoothing operation.
