| pol2cart {geometry} | R Documentation |
Transform polar or cylindrical coordinates to Cartesian coordinates.
Description
The inputs theta, r, (and z) must be the same shape, or
scalar. If called with a single matrix argument then each row of P
represents the polar/(cylindrical) coordinate (theta, r
(, z)).
Usage
pol2cart(theta, r = NULL, z = NULL)
Arguments
theta |
describes the angle relative to the positive x-axis. |
r |
is the distance to the z-axis (0, 0, z). |
z |
(optional) is the z-coordinate |
Value
a matrix C where each row represents one Cartesian
coordinate (x, y (, z)).
