Re: Filling a matrix

[Athanasius]

Hello David92,

The main problem is this line:

@valueArray = ([$version,$totSP]);

which simply overwrites the whole array on each iteration of the innermost loop. Replace it with this:

push @valueArray, [$version, $totSP];

Also, please put

use strict;
use warnings;

at the head of your script, and declare all variables explicitly as lexicals by using my:

for my $folderId (keys %hash)
{
    for my $customer (keys %{$hash{$folderId}})
    {
        for my $version (keys %{$hash{$folderId}{$customer}})
        {
            my $totSP = $hash{$folderId}{$customer}{$version}{totSP};
            push @valueArray, [$version, $totSP];
        }
    }
}

— and note how much easier it is to read code which is indented consistently. ;-)

Hope that helps,
