before projinv, I made this plot.
and after projinv, I plotted this polyshape in geoplot, and i found that there are unconncted lines.
so i added the first coordinates after the end coordinates.
ex) 1 2 3 4 5 1 NaN ~~~
the results seem not to have unconnected line. but it's still not filled with color.
[IFR_lat_merged IFR_lon_merged] = projinv(p,IFR_cutout.Vertices(:,1),IFR_cutout.Vertices(:,2));
IFR_cutout = geopolyshape(IFR_lat_merged,IFR_lon_merged)
Thanks
