\description{
\command{\link{RMprod}} is a non-stationary covariance model given by
\deqn{C(x,y) = \langle \phi(x), \phi(y)\rangle }{C(x,y) = \langle \phi(x), \phi(y)\rangle.}
}
\usage{
RMprod(phi, var, scale, Aniso, proj)
}
\arguments{
\item{phi}{any function of class \code{\link[=RMmodel-class]{RMmodel}}
}
\item{var,scale,Aniso,proj}{optional arguments; same meaning for any
\command{\link{RMmodel}}. If not passed, the above
covariance function remains unmodified.}
}
%\details{}
\value{
\command{\link{RMprod}} returns an object of class \code{\link[=RMmodel-class]{RMmodel}}.

\note{
Do not mix up this model with \command{\link{RMmult}}.
See also \command{RMS} for a simple, alternative method to set
an arbitrary, i.e. location dependent, univariate variance.
