\title{Virtual Class "dsparseMatrix" of Numeric Sparse Matrices}
\description{The Class \code{"dsparseMatrix"} is the virtual (super) class of
  all numeric sparse matrices.

    \item{\code{Dim}:}{the matrix dimension, see class \linkS4class{Matrix}.}
    \item{\code{Dimnames}:}{see the "Matrix" class.}
    \item{\code{x}:}{a \code{\link{numeric}} vector containing the
      (non-zero) matrix entries.}
    \item{\code{factors}:}{Object of class \code{"list"} - a list
      of factorizations of the matrix. }

\section{Extends}{
  Class \code{"dMatrix"} and \code{"sparseMatrix"}, directly.\cr
  Class \code{"Matrix"}, by the above classes.
