\begin{Description}\relax
Compute points on the ellipsoid boundary, mostly for drawing.
\end{Description}
\begin{Usage}
\begin{verbatim}
## S3 method for class 'ellipsoid':
predict(object, n.out=201, ...)
ellipsoidPoints(A, d2, loc, n=201)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{object}] an object of class \code{ellipsoid}, typically from
\code{\Link{ellipsoidhull}()}.
\item[\code{n.out,n}] the number of points to create.
\item[\code{A, d2, loc}] arguments of the auxilary \code{ellipsoidPoints}, see below.
\item[\code{...}] passed to and from methods.
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
Note \code{ellipsoidPoints} is the workhorse function of the
\code{predict.ellipsoid} method; the class of \code{object} is not
checked; it must solely have valid components \code{loc} (length \eqn{p}{}),
the \eqn{p \times p}{p x p} matrix \code{cov} (corresponding to
\code{A}) and \code{d2} for the center, the shape (``covariance'')
matrix and the squared average radius or distance.
\end{Details}
\begin{Value}
a numeric matrix of dimension \code{n.out} times \eqn{p}{}.
\end{Value}
\begin{SeeAlso}\relax
\code{\Link{ellipsoidhull}}, also for examples.
