\alias{cart2sph}
\title{Transform Cartesian to spherical coordinates}
\usage{
cart2sph(x, y = NULL, z = NULL)
}
\arguments{
\item{x}{x-coordinates or matrix with three columns}
\item{y}{y-coordinates (optional, if \code{x}) is a matrix}
\item{z}{z-coordinates (optional, if \code{x}) is a matrix}
}
\value{
Matrix with columns:
\item{\code{theta}}{the angle relative to the positive x-axis}
\item{\code{phi}}{the angle relative to the xy-plane}
\item{\code{r}}{the distance to the origin \code{(0, 0, 0)}}
}
\description{
If called with a single matrix argument then each row of \code{c}
represents the Cartesian coordinate (\code{x}, \code{y}, \code{z}).
