Cartesian to spherical coordinate conversion.

Cartesian to spherical coordinate conversion.

cartesian2spherical(x, y = NULL, z = NULL)

Arguments

y	a vector of y coordinates
z

Value

A vector of three spherical coordinates \(r, theta, phi\) of a point represented as \(x, y, z\) in Cartesian coordinates.
