NAME
Bio::Matrix::PhylipDist - A Phylip Distance Matrix object
SYNOPSIS
my $dist = Bio::Tools::Phylo::Phylip::ProtDist->new(
-file=>"protdist.out",
-program=>"ProtDist");
my $dist = Bio::Tools::Phylo::Phylip::ProtDist->new(
-fh=>"protdist.out",
-program=>"ProtDist");
my $distance_value = $dist->get_entry('ALPHA','BETA');
my @columns = $dist->get_column('ALPHA');
my @rows = $dist->get_row('BETA');
my @diagonal = $dist->get_diagonal();
print $dist->print_matrix;

DESCRIPTION
Simple object for holding Distance Matrices generated by the following Phylip programs:
1) dnadist 2) protdist 3) restdist
It currently handles parsing of the matrix without the data output option.
