\title{
Evaluate the Hessian matrix of a monotone function
}
\description{
Evaluates the hessian or second derivative matrix of a monotone function 
with respect to the coefficients definingthe log-first derivative $W(t)$ 
at each of a set of argument values.
}
\usage{
monhess(x, Wfd, basislist)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{x}{A numerical vector at which function and derivative are
                 evaluated.}
  \item{Wfd}{A functional data object.}
  \item{basislist}{A list containing values of basis functions.}
}
\value{
A three dimensional array with first dimension corresponding to argument values 
and second and third dimensions to number of basis functions defining $W$.
