\description{This is the virtual class of all dense numeric (i.e.,
  \bold{d}ouble, hence \emph{\dQuote{ddense}}) S4 matrices.

  Its most important subclass is the \code{\linkS4class{dgeMatrix}} class.
  %% and now say what the difference is ! __ FIXME __
}
\section{Extends}{
  Class \code{"dMatrix"} directly;
  class \code{"Matrix"}, by the above.
}
\section{Slots}{
  the same slots at its subclass \code{\linkS4class{dgeMatrix}}, see
  there.
}
\section{Methods}{
  Most methods are implemented via \code{as(*, "dgeMatrix")} and are
  mainly used as \dQuote{fallbacks} when the subclass doesn't need its
  own specialized method.

  Use \code{\link{showMethods}(class = "ddenseMatrix", where =
      "package:Matrix")} for an overview.
