in thread perl error

@Matrix[$row($a+180)][$column($b+180)] += 1;

should be something like

$Matrix[$row($a+180)][$column($b+180)] += 1;

    He definitely wants $row[$a+180] rather than $row($a+180) in the matrix operation, but I really think he wants just $a+180, since he never fills @row and @column with anything other than 0.
