PURPOSE ^

geodetic2enu convert from geodetic to ENU coordinates

SYNOPSIS ^

function [e, n, u] = geodetic2enu(lat, lon, alt, lat0, lon0, alt0, spheroid, angleUnit)

DESCRIPTION ^

geodetic2enu    convert from geodetic to ENU coordinates

 Inputs
 ------
 lat,lon, alt:  ellipsoid geodetic coordinates of point under test (degrees, degrees, meters)
 lat0, lon0, alt0: ellipsoid geodetic coordinates of observer/reference (degrees, degrees, meters)
 spheroid: referenceEllipsoid parameter struct
 angleUnit: string for angular units. Default 'd': degrees

 outputs
 -------
 e,n,u:  East, North, Up coordinates of test points (meters)
