\title{Polynomial Roots}
\description{
Computes the roots of the polynomial \code{p}.
}
\usage{
roots(p)
}
\arguments{
\item{p}{vector of real numbers representing the polynomial}
}
\details{
For solution the function computes the eigenvalues of the companion matrix.
At the moment, only real coefficients are allowed.
}
\value{
a vector holding the roots of the polynomial
