Re: Handling a 450,000x450,000 array with Perl

Hi.

Thank you very much for your quick answers. I try to handle data from a
450x450 meter surface.

I've got 100,000 elements distributed on this surface, and each
square millimeter can hold one or more elements. So the array to create
is a sparse one: most of square millimeters holds zero elements, and
the rest, 20 or less.

I'm trying to find the square meter with more elements inside.

So then, I assume the square meters' must be rotationally aligned parallel
to the axes of the millimeter scale. But can one square meter "slide" by
a millimeter in order to make another square meter, or does it have to
slide by a full meter? I.e. can the potential square meters overlap each
other?
