Exporting to text file - adding a header

Hi!

I was just wondering what the best way to add a header would be to a text file I am exporting using the following command provided by a kind member of another forum:

x = [1:5];
y = rand(1,5);

fileID = fopen('yourfile.txt','w');
for i = 1:length(x)
    fprintf(fileID,'%s\t%d\t%d\t%f\n', 'Test', x(i),x(i),y(i));
end
fclose(fileID);

This creates a text file with the format:

Test    1   1   0.655741
Test    2   2   0.035712
Test    3   3   0.849129
Test    4   4   0.933993
Test    5   5   0.678735

And I just need to be able to add a text header to the very first line of the .txt file consisting of a few words:

      Word1 Word2 Word3
      Test    1   1   0.655741
      Test    2   2   0.035712
      Test    3   3   0.849129
      Test    4   4   0.933993
      Test    5   5   0.678735

Thanks for any help!
