This is my code. It works however, does not include the title on the new text file and doesn't include when it was created. Please help.

Change
title('Meda 05 Temperature Climatology');
to
report_date = datetime('now', 'Format', 'yyyy-MM-dd');
fprintf(FID, 'Meda 05 Temperature Climatology at %s\n', report_date);
Change the Format to whatever is appropriate for your situation.
