how to resolve undefined function?

You do not appear to be using the correct syntax when calling this function. I suggest reading through the comments at the top of the function to be sure you are supplying it with the expected input values.

Thanks, Sir Cris. I've checked what you and the below error appears

It is just the first time i get this error. I usually can add/donload toolboxes to matlab easily.

'asc2eph' is not found in the current folder or on the MATLAB path, but exists in:

/Users/eyounils/Library/Application Support/MathWorks/MATLAB Add-Ons/Collections/JPL Ephemeris manager/@Ephem

Change the MATLAB current folder or add its folder to the MATLAB path.

This is not a MathWorks created function. Someone else has created and shared it with the community.

I would suggest adding the folder " /Users/eyounils/Library/Application Support/MathWorks/MATLAB Add-Ons/Collections/JPL Ephemeris manager" and all subfolders to your MATLAB Path.

See here: https://www.mathworks.com/help/matlab/matlab_env/add-remove-or-reorder-folders-on-the-search-path.html
