You are analyzing a train timetable (you have some time to kill since you just missed your train!) How many trains depart each day of the week? (submit the results as a table with the days of the week and number of trains)Example<pre class="language-matlab">DepTime = datetime(2016,11,1,[6 8 9],[22 51 05],0)';
ArrTime = datetime(2016,11,1,[9 10 12],[17 32 09],0)';
Destination = categorical({'BOS';'NYC';'BOS'});
tt = timetable(DepTime,Destination,ArrTime)
tt = 
 DepTime Destination ArrTime
