I am reading the names of all the images and then I want to write the name to a text file with a newline. Like
pic1.png
pic2.png
But my code below cannot new line. How to new line help thanks.
imagefiles = dir('*.jpg');
nfiles = length(imagefiles); % Number of files found
fileID = fopen('Label.txt','wt');
for ii=1:nfiles
currentfilename = imagefiles(ii).name;
name = sprintf(currentfilename,'\r\n');
fprintf(fileID,name);
end
fclose(fileID);

for ii=1:nfiles
currentfilename = imagefiles(ii).name;
fprintf(fileID, '%s\n', currentfilename);
end
Do not use \r\n however. You opened the file with 'wt' which is text mode, and if you are on an MS Windows system that automatically means that all \n should be transformed into \r\n when you write them. If you might be executing the code on non-MS Windows systems and you need to force \r\n then you should be opening in binary mode 'w' instead of 'wt' and in that case do use \r\n
