Using MATLBA's Mapping Toolbox, I am loading this map (see Image):
In my case, I am plotting it from the south pole, with the south pole in the origin of coordinates.
I need to display the meridian axes around the circular image of the Moon (0 degrees at the top, 180 at the bottom, etc).
Is there any way I could do it? I have been going through many Matlab tutorials and Mathworks answers but have not found anything that specifically addresses this issue. Thank you!

Andrew Bliss has a function called polarstereo_fwd, which might do what you need. Convert all your lats and lons to x and y values, then drawing a meridian is a simple as drawing a vertical line at x = 0.
