Read Multiple Files with While Loop

I have about 20 files that I need to read and manipualte data. How would I write a while loop so that it will read the file, extract data, then continue to read the next file, etc. ?

[Walter Roberson]

Is there a particular reason to use a while loop instead of a for loop?

The standard approach is to use a FOR loop:

fn = dir("*.dat");          % or your file name pattern
for i=1:length(fn)
    fn_c = fn(i).name       % current filename to be processed
    % do processing for fn_c
       
end
