As has already been explained by others, a reference must be used in place of an array itself.

I'd like to add just one thing. For performance reasons, i'd rather change the sub mult to return the array reference rather than the array itself. Also, pass an array reference as the second param to mult instead of an array.

sub mult { my ($a, $b) = @_; # dereference the array, process it and create a new array .... return \@c; } ## Assuming that the array @b is a 2D array too for $i (0..$N){ push @results, mult($a, $b[$i]); }

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
