```Dear Friends,

Further, I want to compute the APEn values for the multiple files in a
folder. In particular, along with the loop for the columns in one data file
(through the code that I mentioned above), I have to write a loop for the
multiple files (having same dimensions) in a folder.

But, I am not getting a proper idea for writing the double loop (i.e. one
for the multiple columns of one excel sheet and other for the multiple
excel sheets of a folder).
