NAME

ObjStore::Lib::PDL - Persistent PDL-compatible matrices

SYNOPSIS

    use PDL::Lite;
    use ObjStore::Lib::PDL;

    begin 'update', sub {
      my $pdl = ObjStore::Lib::PDL->new($near,
                          { Datatype => PDL::float(), Dims => [3,3] });

      $pdl->slice(":,4")->clump(2) *= 2;  #or whatever
    };
    die if $@;

DESCRIPTION

The main thing of interest is that dimensions are arranged in memory such that the first dimension is the most packed. For example, in a PDL of dimensions [2,3] the layout is as follows:

  [0,1]
  [2,3]
  [4,5]

Be aware that this memory layout convention is dependent on the implementation of PDL. It is, however, very unlikely to change.
