Input Arguments

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.
