Thread Subject: Creating a Log, xml or text file

Hi,

How to create a log, xml or text file?

I'm creating a small test application for my research using which images are displayed and the viewer will rate them based on particular scale. I want to save the rating/grading for each picture in a form of text file.

Can anyone help

thanks

You can definitely use the fprintf function. The help documentation should have enough explanation on that.

Thank you for your reply. Helpped alot. But I still couldn't figure out how to append the text within the same file.

global fid
fid = fopen('log.txt','wt');
fprintf(fid, 'text line number 1 \n');

Awaiting

When you open the file with fopen, you should write 'at' instead of 'wt'. 'a' stands for append.
