Only the upper triangle or the lower triangle is stored.} \section{Objects from the Class}{ Objects can be created by calls of the form \code{new("dsyMatrix", ...)}. } \section{Slots}{ \describe{ \item{\code{uplo}:}{Object of class \code{"character"}. Must be either "U", for upper triangular, and "L", for lower triangular.} \item{\code{x}:}{Object of class \code{"numeric"}. The numeric values that constitute the matrix, stored in column-major order.} \item{\code{Dim}:}{Object of class \code{"integer"}. The dimensions of the matrix which must be a two-element vector of non-negative integers.} \item{\code{norm}:}{Object of class \code{"numeric"}. A named numeric vector of norms of the matrix. Some possible components are \code{"O"}, the one norm; \code{"I"}, the infinity norm; \code{"F"}, the Frobenius norm; and \code{"M"}, the maximum absolute value.} \item{\code{rcond}:}{Object of class \code{"numeric"}. A named numeric vector of reciprocal condition numbers in either the 1-norm \code{"O"} or the infinity norm \code{"I"}.} \item{\code{factors}:}{Object of class \code{"list"}. A named list of factorizations that have been computed for the matrix.} } } \section{Extends}{ Class \code{"dgeMatrix"}, directly.
