in reply to Get hash values in multidimensional array to populate Term document matrix

Hi,

your @arr array has never been populated with anything. So: 

for my $i (0 .. $#arr){

isn't going to loop on anything.

I would suggest that you use the following pragmas: 

use strict;
use warnings;

as this will enable the compiler to point out at some of your probable mistakes.

Update: Sorry I probably looked at it too quickly, I missed the last push line.

    It is for me. When I run the 1st code snippet (no strictures), I see something in @arr: 
    use Data::Dumper; print Dumper(\@arr);
$VAR1 = [
          [
            {
              'key' => 12,
              'lop' => 9,
              'pl' => 1
            },
            {
              'key' => 12
            }
          ]
        ];

    What happens when you run it? The 2nd snippet has compile errors for me.
