文件included in the datastore, resolved as a character vector, cell array of character vectors, string scalar, or string array, where each character vector or string is a full path to a file.
这地点争论数据存储函数定义文件property when the datastore is created. The地点argument contains full paths to files on a local file system, a network file system, or a supported remote location such as Amazon S3™, Windows Azure®BLOB存储和HDFS™。有关更多信息,请参阅使用远程数据。
这些文件必须是垫子文件或序列文件写功能。
Example:[“ c:\ dir \ data \ file1.ext”;“ c:\ dir \ data \ file2.ext”]
替代文件系统根路径,指定为由名称值参数组成的"AlternateFileSystemRoots"以及字符串向量或单元格数组。利用"AlternateFileSystemRoots"when you create a datastore on a local machine, but need to access and process the data on another machine (possibly of a different operating system). Also, when processing data using the Parallel Computing Toolbox™ and theMATLAB®Parallel Server™,并且数据存储在您的本地计算机上,并具有在不同平台云或群集机上可用的数据的副本,您必须使用"AlternateFileSystemRoots"to associate the root paths.
要关联到数据存储的多组根路径,请指定"AlternateFileSystemRoots"as a cell array containing multiple rows where each row represents a set of equivalent root paths. Specify each row in the cell array as either a string vector or a cell array of character vectors. For example:
指定"AlternateFileSystemRoots"as a cell array of string vectors.
