how to read txt files in the same folder

I have text files in a folder. Their names are

BC_1.txt, BC_2.txt, BC_3.txt, ..., BC_100.txt.

I would like to know how to read all files with a loop. Thank you so much.

If you want to read the files in alpha-numeric order then you can either:

1. generate the names using sprintf (as shown on the page madhan ravi linked to), or
2. use dir to get the actual filenames, and then sort them. The simplest way to do this is to download my FEX submission natsortfiles, and use it like this:

S = dir('BC*.txt');
C = natsortfiles({S.name});
for k = 1:numel(C)
    F = C{k}
    ... do whatever with filename F
end

txtfiles = dir('*.txt') ;
N = length(txtfiles) ;
for i = 1:N
     thisfile = txtfiles(i).name ;
    % do waht you want
end
