\name{matrix.csc.hb-class}
\title{Class "matrix.csc.hb" - Column Compressed Sparse Matrices stored in Harwell-Boeing Format}
\docType{class}
\alias{matrix.csc.hb-class}
\alias{show,matrix.csc.hb-method}
\alias{show,matrix.ssc.hb-method}
\description{
A class consisting of the coefficient matrix and the right-hand-side of a
linear system of equations, initial guess of the solution and the exact
solutions if they exist stored in external files using the
Harwell-Boeing format.
}
\section{Objects from the Class}{
Objects can be created by calls of the form \code{new("matrix.csc.hb", ...)}.
}
\section{Slots}{
\describe{
\item{\code{ra}:}{Object of class \code{numeric}, ra component of the csc or ssc format of the coefficient matrix, X.}
\item{\code{ja}:}{Object of class \code{integer}, ja component of the csc or ssc format of the coefficient matrix, X.}
\item{\code{ia}:}{Object of class \code{numeric}, ia component of the csc or ssc format of the coefficient matrix, X.}
\item{\code{rhs.ra}:}{Object of class \code{numeric}, ra component of the right-hand-side, y, if stored in csc or
ssc format; right-hand-side stored in dense vector or matrix otherwise.}
\item{\code{guess}:}{Object of class \code{numeric} or \code{NULL} vector of the initial guess of the solutions if they exist;
a null vector otherwise.}
\item{\code{xexact}:}{Object of class \code{numeric or NULL} vector of the exact solutions, b, if they exist; a null vector otherwise.}
\item{\code{dimension}:}{Object of class \code{integer}, dimenson of the coefficient matrix, X.}
\item{\code{rhs.dim}:}{Object of class \code{integer}, dimenson of the right-hand-side, y.}
\item{\code{rhs.mode}:}{Object of class \code{character or NULL} storage mode of the right-hand-side; can be full storage or
same format as the coefficient matrix.}
}
