matlab对文件进行重命名

files = dir('*.dat');
len = length(files);
 
for i = 1:len
    oldname = files(i).name;
    seq = mat2str(i);
    newname = ['a',seq,'.dat'];
    command = ['rename' 32 oldname 32 newname];
    
    status = dos(command);
    if status == 0
        disp([oldname,'已被重命名为',newname]);
    else
        disp([oldname,'重命名失败']);
    end
end
