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);

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
...
