27 Aug 2009 Solar Azimuth and Elevation Estimation Predict the topocentric solar position defined by geodetic lat, lon, Alt, and a universal time Author: Darin Koblick Phil

Ropey when using vector times: (line 36 generates a vector eccentricity: line 42 then requires an edit to force array multiply not matrix multiply). Still unable to get vector time version to agree with loop version....
As Mr. Picky, I would prefer time argin to be Matlab datenum, not string.
HOWEVER, this is the only code I've found that gives Azimuth round the full 360: most are 0-180 and it's up to you to find if its in the east or west... due to using code like

Thanks

Hi, I would like to know what are the local coordinate frame zero points and turning directions. I'm not even sure what are the official ones...

hi,

where are you using
LunarPLon
LunarPLat
LunarPDist

.... if I dont use these....will it affect the Az, El values.

Excellent function, it's fast, compact, and easily modified for my particular needs. Thank you very much! BTW, I compared it with sun position tables, (http://www.srrb.noaa.gov/highlights/sunrise/azel.html) and it does very well.
