\title{Log-linearly Spaced Sequences}
\description{
Generate log-linearly spaced sequences.
}
\usage{
logspace(x1, x2, n = 50)
logseq(x1, x2, n = 100)
}
\arguments{
\item{x1}{numeric scalar specifying starting point}
\item{x2}{numeric scalar specifying ending point}
\item{n}{numeric scalar specifying number of points to be generated}
}
\details{
These functions will generate logarithmically resp.
exponentially spaced points between \code{x1} and \code{x2} resp.
\code{10^x1} and \code{10^x2}.
If \eqn{n < 2}, the result will be the ending point \code{x2}. For
\code{logspace()}, if \code{x2 = pi}, the endpoint will be \code{pi}
and not \code{10^pi}!
}
\value{
vector containing \code{n} points between \code{x1} and \code{x2} inclusive.
