Math::MatrixReal::Ext1 - Minor extensions to Math::MatrixReal

Just scratching a couple of itches for functionality in Math::MatrixReal. [At the time I wrote this (2001) Math::MatrixReal was abandoned, but someone has since adopted it. My recent (2005) updates will also hopefully go into Math::MatrixReal, but fo...
