I have a folder named 'means' which has further sobfolders numbered from '1979-2015', each subfolder has 12 files, i want to process each of that file. But how to call this folder , subfolder and further all the files.

        % this is how i am going to process each of these files
        fid1 = fopen(filename, 'r', 'ieee-le');
        data = fread(fid1, 390963, 'int16');
        tdata = reshape(data,3,361,361);
        fclose(fid1);

        u = squeeze(tdata(1,:,:)./10);
        v = squeeze(tdata(2,:,:)./10);
        error = tdata(3,:,:);

        nu = u.*cos(rlong) + v.*sin(rlong);
        nv = -u.*sin(rlong) + v.*cos(rlong);

You can use a function built for this. It's called genpath() and generates a list of all subfolders below the specified folder. Attached is an example where I go into all subfolders and then use dir() to get a list of files living in that folder.

Image Analyst I am using this already, you posted this on my previous question.It works totally fine, but if i had to rewrite a program at my own, i don't think i would be able to write that at my own... that's why I am kind of looking for an easier way to do the same thing

I don't understand this. If I wanted to do something and someone showed me a way that I hadn't thought of, I would use it. If it was somewhat more clever or tricky than I would have thought up on my own, I might still use it as long as it make sense and I was able to understand/follow it. But whatever - do what you want. There are more complicated ways to get the sub-directories using just dir() instead of genpath() if you want to discover it or develop it on your own. Anyway, good luck.

I am already using the one that you have given me..But just trying to figure out the other ways of doing the same thing. I appreciate the fact that you are a very good programmer.
