You are closing the file in the loop. close the file after the loop. I assume the below should work.

function read_datapattern(filename)
fid = fopen(filename,'rt');
if fid < 0
  error('error opening file %s\n\n',filename);
end
pattern = fgets(fid);
for n = 1:32767
  nextline = fgets(fid);
  pattern = strcat(pattern, nextline);
fprintf(pattern);
fprintf('\n');
end
fclose(fid);

you mean export data to text file

 m=[1 2 3 4 5 6 6 6 7 8 9]
 fid = fopen('data.txt', 'w');
 fprintf(fid, '%d', m); 
 fclose(fid);

works fine

 dlmwrite('file.txt',m,'delimiter',' ')
