\description{The reduced Cholesky decomposition object}
\section{Objects from the Class}{Objects can be created by calls of the form \code{new("inchol", ...)}.
or by calling the \code{inchol} function.}
\section{Slots}{
\describe{
\item{\code{.Data}:}{Object of class \code{"matrix"} contains
the decomposed matrix}
\item{\code{pivots}:}{Object of class \code{"vector"} contains
the pivots performed}
\item{\code{diagresidues}:}{Object of class \code{"vector"} contains
the diagonial residues}
\item{\code{maxresiduals}:}{Object of class \code{"vector"} contains
the maximum residues}
}

\section{Extends}{
Class \code{"matrix"}, directly.

\section{Methods}{
\describe{
\item{diagresidues}{\code{signature(object = "inchol")}: returns
the diagonial residues}
