\description{This is the virtual class of all dense (S4) matrices.
  It is the direct superclass of
  \code{\linkS4class{ddenseMatrix}},
  \code{\linkS4class{ldenseMatrix}}
}
\section{Extends}{
  class \code{"Matrix"} directly.
}
\section{Slots}{
  %% MM :adding the slots here because "R CMD check" gave warning
  %%  _WHY_ was this not necessary in ./ddenseMatrix-class.Rd ?
  %%   or ./sparseMatrix-class.Rd  ???
  exactly those of its superclass \code{"Matrix"}, i.e.,
  \describe{
    \item{\code{factors}:}{Object of class \code{"list"} - a list
      of factorizations of the matrix.}
    \item{\code{Dim}:}{length 2 \code{"integer"}}
    \item{\code{Dimnames}:}{\code{"list"} of length 2,}
  }
  %% not sufficient: \code{Dim}, and \code{Dimnames},
  see \code{\linkS4class{Matrix}}.
}
