topocentric_ra_and_​dec_from_r(r,lla,t)

Topocentric equatorial system right ascension and the declination from the geocentric equatorial

Geocentric Coordinates (ECI) to Topocentric equatorial system
This function calculates the Topocentric equatorial system
right ascension and the declination from the geocentric
equatorial position vector
r - position vector in meters
t - Universal Coordinated Time i.e . [2017 02 02 11 48 28];
lla - Latitude, longitude, altitude (LLA) coordinates M-by-3 array
degrees and meters
ra - Topocentric right ascension (degrees)
dec - Topocentric declination (degrees)
