\description{
Power of a polynomial.
}
\usage{
polypow(p, n)
}
\arguments{
\item{p}{vector representing a polynomial.}
\item{n}{positive integer, the exponent.}
}
\details{
Uses \code{polymul} to multiply the polynomial \code{p} \code{n} times
with itself.
}
\value{
Vector representing a polynomial.
}
\note{
There is no such function in Matlab or Octave.
