You are attempting to read a file in the current directory:
S = shaperead(shapefile.name);
That is, you are not taking into account the location of that file.
You should specify an absolute or relative path to the file, e.g.:
file_name = fullfile(shapefile.folder,shapefile.name);
S = shaperead(file_name);
d = uigetdir(pwd, 'Select a folder');
assert(~isnumeric(d),'No folder selected')
shapefiles = dir(fullfile(d, '*.shp'));
for n = 1:length(shapefiles)
shapefile = shapefiles(n);
file_name = fullfile(shapefile.folder,shapefile.name);
disp(file_name);
S = shaperead(file_name);
polygon = polyshape([S.X], [S.Y]);
% Create a logical mask
logical_mask = inpolygon(lon, lat, polygon.Vertices(:, 1), polygon.Vertices(:, 2));
% ...
end
