NAME

Bio::NEXUS::MatrixBlock

SYNOPSIS

This module is the super class of Characters, Unaligned, and Distances block classes, and indirectly it is a super-class of Data and History blocks, which are both sub-classes of Characters blocks. These sub-classes inherint the methods within this module. There is no constructor, as a MatrixBlock should not exist that is not also one of the sub-class block types.

DESCRIPTION

Provides functions used for handling blocks that have matrices.
