please any one can explain this to me

n= fopen('stopword.txt','r');
m = textscan(n,'%s',100);

   f = fopen('gg.txt','r');
   I = textscan(f,'%s',100);
   ll=strrep(I{1},'.','');

d=ll;
u=unique(d);

   l=m{1};

   for i=1:length(d)   
   x = strmatch(d(i),l);

c=0;  
 if isempty(x)
  for j=1:length(u) 
      x = strmatch(d(i),d(j))
      if x==1  
          c=c+1; 
      end
  end 
 end
 feq(i)=c;  
 end

       [n m1]= sort(feq,'descend')

It's MATLAB code. And it appears to read two files, that you forgot to attach, and do some replacing, matching, and sorting. A wild guess is that it's converting Euro numbers that use commas instead of decimal points to numbers with decimal points. Other than that I'd need the file to figure it out, and you can do that as well as we can.

If you don't know what this code even does, then why did you get it and why are you trying to run it? If you can find the author, scold them for not putting in any comments and ask them to go through it with you as you add comments to their code.
