cart2polar: Turns Cartesian coordinates into polar coordinates

In AndrewHFarkas/EMEGShelper: What the Package Does (One Line, Title Case)

Turns Cartesian coordinates into polar coordinates

Description

This function takes Cartesian coordinates and turns them into polar/geographic coordinates. Finding these positions are necessary for creating ecfg configuration files for EMEGS such that the software knows its three dimensional location on a sphere. Assumes radius of one, X is right ear (negative) to left ear (positive), Y positive toward nose , and Z is 1 at Cz. Spherical coordinates are returned in radians and degrees. Theta is 0 at Cz pi at other pole. Phi is zero at right ear, pi/2 (90°) at nose, pi (180°) at left ear, 3/2*pi (270°) at Oz.

Usage

cart2polar(x_coor, y_coor, z_coor)

Arguments

x_coor	x coordinate between -1 and 1
y_coor	y coordinate between -1 and 1
z_coor	z coordinate between -1 and 1

Value

Returns a named vector with theta and phi in degrees and radians
