How to read several text files in a loop

Hello Guys, I have a problem that I cannot understand how fopen, fid and other similar syntax are working. But I know I have to seek for the answer to my question around them :-)

Well, here is my question. Assume I have 10 text files with filenames of 1.txt , 2.txt, 3.txt and etc. I have a code which perfectly works for each single filename. However, I need to run the code 10 times seperately to do my desired calculations for these 10 files. Is there any way to run the code for once and it starts loading each file working through it and then goes to the next file?

For the time being, I wrote my code in this order which is of course so annoying:

    filename = '1.txt';
    A = load (filename); 
    % doing some calculations
    print the output for 1.txt
    clear
    clc
    filename = '2.txt';
    A = load (filename); 
    % doing some calculations
    print the output for 2.txt
    clear
    clc
    filename = '3.txt';
    A = load (filename); 
    % doing some calculations
    print the output for 3.txt

Thank you in advanced.

Processing a sequence of file is comprehensively explained in the wiki, together with example code: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

Basically you need to do something like this (pseudocode):

for k = 1:10
    filename = sprintf('%d.txt',k);
    A = load(filename); 
    % doing some calculations
    print the output for k.txt
end

use the import tool. it will help you create function file and then you can call the function whenever u want
