clcclearSOURCE_DIR='G:/watecrop';fid=fopen('water_train.txt','w');fid2=fopen('water_val.txt','w');Path=dir(SOURCE_DIR);for i=3:length(Path)   sub_dir = Path(i).name;   pi = fullfile(SOURCE_DIR, sub_dir);   local_lujing=dir(pi);   label=i-3;   u1=randperm(length(local_lujing)-2)+2;             val_name=local_lujing(u1(1)).name;             aaa=fullfile(sub_dir,val_name)             fprintf(fid2,'%s',aaa);             fprintf(fid2,' ');             fprintf(fid2, num2str(label));             fprintf(fid2,'\n');       for j=2:length(u1)                   img_name = local_lujing(u1(j)).name;             bbb=fullfile(sub_dir,img_name)             fprintf(fid,'%s',bbb);             fprintf(fid,' ');             fprintf(fid, num2str(label));             fprintf(fid,'\n');       end      endfclose(fid);fclose(fid2);

这里需要说明的是：matlab在linux下和windows下
