Hi, I am looking for a script or function for moon phase and position with time, lat and lon as inputs. I had a a quick look on FEx and couldn't see anything that easily fits. Anyone aware of any matlab code or other that I can easily call for this information?

Hi,
Have you seen the Moon Phases File by Meysam Mahooti? https://de.mathworks.com/matlabcentral/fileexchange/55270-moon-phases
It already calculates the Moon Phases for any given Year. I am not sure why you need the lon and lat inputs since the lunar phases (new moon, full moon, etc) only depend on the position of the earth moon and sun. They don't depend where you are on earth. It just affects the angle from which you see the moon. Of course that might make a difference but I am sure you could add this to the calculation.
I hope this helped,
Matthias

I also need Moon azimuth and elevation position with time, lat and lon as inputs! We don't need that for phase calculation, but just to know where the Moon is. I tried the link:
but that gives the 3D carthesian position of the Moon. It dosn't give Moon azimuth and elevation for a given location on Earth.
