matlab dir命令

DIR List directory.

    DIR directory_name lists the files in a directory. Pathnames and

    wildcards may be used.  For example, DIR *.m lists all the M-files

    in the current directory.

 

    D = DIR('directory_name') returns the results in an M-by-1

    structure with the fields: 

        name    -- Filename

        date    -- Modification date

        bytes   -- Number of bytes allocated to the file

        isdir   -- 1 if name is a directory and 0 if not

        datenum -- Modification date as a MATLAB serial date number.

                   This value is locale-dependent.
