\title{Class "inchol" }
\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
