tye has written a tool that should serve your purpose. Have a look at mapcar
use mapcar;
my @matrix = (
[ qw(ab cd ef gh)],
[ qw(ij kl mn op)],
[ qw(qr st uv wx)]
);
my @transposed = mapcar {[@_]} @matrix;
print join( " ", @$_), $/ for @transposed;
__END__
ab ij qr
cd kl st
ef mn uv
gh op wx
Update
mapcar is now a function in tye's Algorithm::Loops.
The above example would becpme:
use Algorithm::Loops qw(MapCar);
my @matrix = (
[ qw(ab cd ef gh)],
[ qw(ij kl mn op)],
[ qw(qr st uv wx)]
);
my @transposed = MapCar {[@_]} @matrix;
print join( " ", @$_), $/ for @transposed;
With exactly the same result.

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).
