fin = fopen('E:/Personal/Desktop/55.txt','wt');
imgDataPath = 'E:/Personal/Desktop/zhong/';

outdir = '5';%写路径
imgDataDir = dir(imgDataPath); % 遍历所有文件

for i = 3:length(imgDataDir)
imgDir = dir([imgDataPath,'/', imgDataDir(i).name '/*.jpg']); % 遍历所有图片
for j =10:13%写
newname = [outdir,'/',imgDataDir(i).name,'_',imgDir(j).name,' ',imgDataDir(i).name];%写标签路径
fprintf(fin,'%s ',newname);
