fileName — File name string array | character vector | cell array of character vector
File name, specified as a string array, character vector, or cell array of
character vectors. For a local file, fileName can include
a relative path, but the relative path must be in the current folder.
Otherwise, fileName must include a full path. If the file
is stored at a remote location, then fileName must
contain a full path specified as a uniform resource locator (URL). For more
information, see Work with Remote Data.
