\title{Convenience wrapper for ARMA(1,1)}
\usage{
arma11(mesh = NULL, ar = 0, ma = 0, fix_ar = FALSE, fix_ma = FALSE)
}
\arguments{
\item{mesh}{Integer vector or `inla.mesh.1d` object.}

\item{ar}{Numeric length-p vector of AR coefficients in (-1, 1). Defaults to zeros.}

\item{ma}{Numeric length-q vector of MA coefficients in (-1, 1). Defaults to zeros.}

\item{fix_ar}{Logical or length-p logical vector to fix AR coefficients.}

\item{fix_ma}{Logical or length-q logical vector to fix MA coefficients.}
}
\value{
An \code{ngme_operator} object describing an ARMA(1,1) latent
  operator. The object contains the AR precision component \code{K}, the MA
  filter component \code{Z}, integration weights \code{h}, and the
  unconstrained AR and MA parameters used by the optimizer. If \code{mesh} is
  \code{NULL}, returns an \code{ngme_operator_def} specification for delayed
  construction inside \code{f()}.
