\title{Schur product}
\description{
The covariance function is
\deqn{C(x)= M * \phi(x)}
where \sQuote{*} denotes the Schur product, i.e. elementwise
multiplication
}
\usage{
RMschur(phi, M, diag, rhored, var, scale, Aniso, proj)
}
\arguments{
\item{phi}{covariance function of class \code{\link[=RMmodel-class]{RMmodel}}.}
\item{M}{constant \eqn{n \times n}{n x n} covariance matrix of the
same size as multivariate model \code{phi}}
\item{diag,rhored}{alternative way of passing \code{M}:
\code{diag} is a vector of variances, \code{rhored} is a vector
containing the correlations of lower triangle of the \code{M}
}
\item{var,scale,Aniso,proj}{optional arguments; same meaning for any
\command{\link{RMmodel}}. If not passed, the above
covariance function remains unmodified.}
}
\value{
\command{\link{RMschur}} returns an object of class \code{\link[=RMmodel-class]{RMmodel}}
