\name{Matrix.reStruct}
\title{Assign reStruct Matrices}
\usage{
\method{matrix}{reStruct}(object) <- value
}
\alias{matrix<-.reStruct}
\arguments{
\item{object}{an object inheriting from class \code{"\link{reStruct}"},
representing a random effects structure and consisting of a list of
\code{pdMat} objects.}
\item{value}{a matrix, or list of matrices, with the new values to be
assigned to the matrices associated with the \code{pdMat} components
of \code{object}.}
}
\description{
The individual matrices in \code{value} are assigned to each
\code{pdMat} component of \code{object}, in the order they are listed. The
new matrices must have the same dimensions as the matrices they are
meant to replace.
}
\value{
an \code{reStruct} object similar to \code{object}, but with the
coefficients of the individual \code{pdMat} components modified to
produce the matrices listed in \code{value}.
