Yeah, it still gives me the error
"Global symbol "$graph" requires explicit package name at line 39".
The code which I have is 

use strict;
use Graph::Matching;

use Graph::Matching qw(max_weight_matching);

my @sub = [];
my @list = split(',', $ARGV[0]);

#print("@list");

my $n = 0;
my @graph = ();
my $i = 0;
my $j = 0;

for ($i=0; $n<my $graph; $i++)
{
 for ($j=0; $j<=2; $j++)
  {
   $sub[$j] = $list[$n];
   $n++;
  }
 $graph[$i] = \@sub;
@sub = ();
}

Thank very much again!
