How to write a text header in text file? for example in the example below, how to write the header code salay month just once?

Code Salary Month
12   1000   12
14   1020   11
11   1212   9

The code:

fid = fopen('analysis1.txt','wt');
for i=1:10
   array = []; % empty the array
   ....
   array = [code salary month];
   format short g;
   fprintf(fid,'%g\t %g\t %g\n',array); % write to file
end
fclose(fid);

Is there any reason for not using simple solution like following?

...
fid = fopen('analysis1.txt','wt');
fprintf(fid, '%s\t %s\t %s\n', 'Code','Salary','Month');
for i=1:10
   array = []; % empty the array
...

Just to make it easy to copy and paste

fid = fopen('Output.txt','wt');
fprintf(fid, '%s\t %s\t %s\n', 'x','y1','y2');
% have a matrix M(N,3) ready to go
dlmwrite('Output.txt', M,'delimiter', '\t', '-append')
fclose(fid);

Thanks, Here is a script I modified to generate one variable file,

fid = fopen('vout.h','wt');
format short g;

fprintf(fid,' /* Header File for the variable vout */  \n\n' );

fprintf(fid,'int vout[ %g ] = { ' ,length(vout));

for i=1:length(vout)

   fprintf(fid,'%g,',vout(i)); % write to file
end
fprintf(fid,'} ; ');

fclose(fid);
