cartesian_to_spherical: Convert Cartesian coordinates to cpherical coordinates

In spheresmooth: Piecewise Geodesic Smoothing for Spherical Data

Convert Cartesian coordinates to cpherical coordinates

Description

This function converts Cartesian coordinates to spherical coordinates.

Usage

Cartesian_to_Spherical(x)

Arguments

x	A matrix where each row represents a point in Cartesian coordinates.

Details

The Cartesian coordinates (x, y, z) are converted to spherical coordinates (theta, phi). Theta represents the inclination angle (0 to pi), and phi represents the azimuth angle (0 to 2*pi).

Value

A matrix where each row represents a point in spherical coordinates.

Examples

#example1
cartesian_points1 <- matrix(c(1/sqrt(3), 1/sqrt(3), 1/sqrt(3),-1/sqrt(3), 1/sqrt(3), -1/sqrt(3)),
  ncol = 3, byrow = TRUE)
Cartesian_to_Spherical(cartesian_points1)
#example2
cartesian_points2 <- matrix(c(1, 0, 0, 0, 1, 0, 0, 0, 1),ncol = 3, byrow = TRUE)
Cartesian_to_Spherical(cartesian_points2)
