https://uk.mathworks.com/matlabcentral/answers/522591-fill-inside-a-polygon-with-a-color
The data below form an almost-closed curve (the first column is "x" and the second is "y"). I'd like to fill it with color but can't figure out how. The "patch" examples I've found online all seem to use two curves except for the one at the link I added. However, it's too advanced for me and I don't understand how to use it.
patch(x, y,' b',' EdgeColor','none', 'FaceAlpha', 0.1)
This works. It gives me a filled shape. However, there's an outline and the
'EdgeColor','none'
does not get rid of it. I'd like to get rid of the outline and would also like to impose a gradient on the fill color so that it goes from nearly clear at one end to more opaque at the other. That's a secondary goal though. The main thing I want to do is get rid of the outline.
If anyone has any hints, I'd be very grateful!

Thank you very much, Davide. Actually, I just figured out the problem! A silly mistake on my part. Appreciate your patience and Star Strider's.
