PDL (Re: Line intersection, scaled to thousands of points)

[Ea]

PDL (``Perl Data Language'') gives standard Perl the ability to compactly store and speedily manipulate the large N-dimensional data arrays which are the bread and butter of scientific computing.

The gubbins that do the manipulation are written in C for a speed boost, which might help if you can't get around your scaling problems.
