>> f = dir('my_filename.dat');

? ? ? ? 参考上述链接的函数，the C-file has to be compiled before it can be used.
????????At first setup your compiler by "mex -setup", if not done before. Then compile as mentioned ????????in the C-file: "mex -O GetFileTime.c" and "mex -O SetFileTime.c".

? ? ? ? 函数引用：

? ? ? ?Time = GetFileTime(FileName, TimeType（可选）, OutputType（可选）)

? ? ? ? 结果如下：
? ????????? Creation: [2021 11 13 21 11 1.8750]
? ????????? ? Access: [2021 11 13 21 21 20.0600]
? ? ????????? ?Write: [2014 2 12 13 32 18]

应用场景

批量读取文件，确认指定日期后修改的文件；

%设定文件修改检查的时间点
DateString = '2014/02/11/13:33';
formatIn = 'yyyy/mm/dd/HH:MM'; %年月日时分
timeStampCheck = datenum(DateString,formatIn);

%所有m、c类型文件（包括子文件夹）
FileInfo_m = dir('**/*.m');
FileInfo_c = dir('**/*.c');

mergestructs = @(x,y) cell2struct([struct2cell(x),struct2cell(y)],fieldnames(x),1);
FileInfo = mergestructs(FileInfo_m,FileInfo_c);

%显示设定时间点之后更新的文件
idx = [FileInfo.datenum]>timeStampCheck;
{FileInfo(idx).name; FileInfo(idx).date}'
