I created a text file but, need it to include a title and time of when it was created.

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.

close all;
clear all;
clc;

Datafiles = fileDatastore("temp_summary*.txt","ReadFcn",@readMonth,"UniformRead",true);

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.
