NAME

       Array::Group - Convert an array into array of arrayrefs of uniform size N.

SYNOPSIS

         use Array::Group qw( :all );

         @sample = ( 1 .. 10 );
         $rowsize = 3;

         ngroup $rowsize => \@sample ;
         # yields
                (
                   [   1,   2,   3   ],
                   [   4,   5,   6   ],
                   [   7,   8,   9   ],
                   [   10   ]
                 );

         dissect $rowsize => \@sample ;
         # yields
                (
                   [   1,   5,   9   ],
                   [   2,   6,  10   ],
                   [   3,   7   ],
                   [   4,   8   ]
                 );

DESCRIPTION

       The "ngroup" method reformats a list into a list of arrayrefs. It is often used for
       formatting data into HTML tables, amongst other things.

       "dissect()" returns a list of lists where the first element of each sublist will be one of
       the first elements of the source list, and the last element will be one of the last.  This
       behaviour is much more useful when the input list is sorted.

       The key difference between the two methods is that "dissect()" takes elements from the
       start of the list provided and pushes them onto each of the subarrays sequentially, rather
       than simply dividing the list into discrete chunks.

       Both methods can be called as either functions or class methods (to ensure compatibility
       with previous releases), and the array to be reformed can be passed as a reference.

   CONTRIBUTORS
       I would like to thank Alexandr Ciornii for his help in upgrading this distribution's
       format. He took me from using a test.pl file to using the t/ directory and removed some
       old crufty things that were not needed.  He also upgraded the Makefile.PL.
