\begin{Description}\relax
\code{iMatrix} is the virtual class of all \bold{i}nteger
(S4) matrices.  It extends the \code{\LinkA{Matrix}{Matrix.Rdash.class}} class directly.

\code{zMatrix} is the virtual class of all \code{\LinkA{complex}{complex}}
(S4) matrices.  It extends the \code{\LinkA{Matrix}{Matrix.Rdash.class}} class directly.
