Predict the azimuth and elevation of the Sun within +/- 1 degree at any geodetic latitude, longitude and altitude. Due to popular demand, this routine has been vectorized for speed.

Function Call: [Az El] = SolarAzEl('2008/02/18 13:10:00',60,15,0)

Input List:
UTC Date and Time - Use format YYYY/MM/DD hh:mm:ss or MATLAB date vector dimensions can be [N x 1]
Latitude - Site Latitude in degrees -90:90 -> S(-) N(+) dimensions can be [N x 1]
Longitude - Site Longitude in degrees -180:180 W(-) E(+) dimensions can be [N x 1]
Altitude - Site Altitude in km dimensions can be [N x 1]

Output List:
Az - Solar Azimuth angle in degrees [N x 1]
El - Solar Elevation/Altitude Angle in degrees [N x 1]
