Dear Perl Monks,
I am using split to parse a string, and have to write an
array from the contents of the string such that every
element of the array is itself a 3x1 array. The code
looks like this:

use strict;
use Graph::Matching;
use Graph::Matching qw(max_weight_matching);
my @sub = [];
my @list = split(',', $ARGV[0]);
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++;
}
my $graph$i = @sub;
@sub = [];
}

It tell me that there is a syntax error in the line
my $graph[$i] = @sub;

Can anyone please, please help with with this?
Thanks very much!
