<p>PDL ("Perl Data Language") gives standard Perl the ability to
<em>compactly</em> store and <em>speedily</em> manipulate the large
N-dimensional data arrays which are the bread and butter of
scientific computing.</p>
<p>PDL turns Perl in to a free, array-oriented, numerical language similar
to (but, we believe, better than) such commerical packages as IDL and MatLab.
One can write simple perl expressions to manipulate entire numerical arrays
all at once. Simple interactive shells, <tt>pdl2</tt> and <tt>perldl</tt>,
are provided for use from the command line along with the <tt>PDL</tt> module
for use in Perl scripts.</p>
