\description{The Class \code{"dsparseMatrix"} is the virtual (super) class of
all numeric sparse matrices.
}
\section{Slots}{
\describe{
\item{\code{Dim}:}{the matrix dimension, see class \code{"\linkS4class{Matrix}"}.}
\item{\code{Dimnames}:}{see the \code{"Matrix"} class.}
\item{\code{x}:}{a \code{\link{numeric}} vector containing the
(non-zero) matrix entries.}
}
}
\section{Extends}{
Class \code{"dMatrix"} and \code{"sparseMatrix"}, directly.\cr
Class \code{"Matrix"}, by the above classes.
}
% \section{Methods}{
% No methods defined with class "dsparseMatrix" in the signature.
