How to write Multiple data in a single .txt files

Hi I want to write two different outputs in a single .txt file . for example The following code works well . I want to add one more out put .

fid = fopen(['Result/Result',int2str(k),',',int2str(l),',',int2str(m),',',int2str(n),',',',','.txt'], 'w');
                    for i=1:16
                         fprintf(fid,'%d',Trans(i,2));
                         fprintf(fid,',');                       
                    end                                 
                   fclose(fid);

Trans =[0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 ; 4 5 6 7 9 8 10 1 2 3 0 15 12 11 13 14]' % second column gives the result and first column is indexing.

k,l,m,n are different values

Result data is successfully written in .txt file. I want to write only those results whose score are 80 or above

How can I add the arverage in this txt file

A simplification of your code:

FileName = sprintf('Result%d,%d,%d,%d,,.txt', k, l, m, n);
fid = fopen(fullfile('Result', FileName), 'w');
fprintf(fid, '%d,', Trans(:, 2));
fclose(fid);

What does this mean: "I want to write only those results whose score are 80 or above" ?

find average and if it is above 80 then write Trans(:,2) and the average value (both) otherwise donot write Trans(:,2) and its average.
