Hi guys--I'm wondering if you can help me with a basic problem regarding Perl Data Language (PDL). I'm trying to figure out how to read a 2D array of numbers into a piddle so I can do some speedy calculations on it. I tried the following, but I get an error: 

#! /usr/bin/perl -w
use strict;
use PDL;

open PROFILE, "profile" or die "Could not open\n";
my $array_ref;
while (<PROFILE>) {
    push (@{$array_ref}, $_);
}
my $pdl = pdl($array_ref);
print "$pdl\n":

The print does not yield my array, and I get the following error: 

Argument "\x{30}\x{2e}..." isn't numeric in subroutine entry at /usr/l
+ib/perl5/site_perl/5.8.0/i386-linux-thread-multi/PDL/Core.pm line 570
+, <PROFILE> line 1.

If anyone can help me out with this, i'd really appreciate it.
