\title{
Generate a Mesh Grid
}
\description{
Generate two matrices for use in three-dimensional plots.
}
\usage{
meshgrid(x, y = x)
}
\arguments{
\item{x}{numerical vector, represents points along the x-axis.}
\item{y}{numerical vector, represents points along the y-axis.}
}
\details{
The rows of the output array X are copies of the vector x;
columns of the output array Y are copies of the vector y.
}
\value{
Returns two matrices as a list with \code{X} and \code{Y} components.
}
\note{
The three-dimensional variant \code{meshgrid(x, y, z)} is not yet implemented.
