Please read perlreftut, perldsc, perllol, perlref, and (if you'd like) Using Refs.

Your code:

@results[$i][]  = mult($a,@b[$i]);
[download]

should -- I think -- be written as:

$results[$i] = [ mult($a, @b) ];
[download]

or

@{ $results[$i] } = mult($a, @b);
[download]

(Using @foo[$i] is generally incorrect.)
