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

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*

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       
____________________    ___________    ____________________
01-Nov-2016 06:22:00    BOS            01-Nov-2016 09:17:00
01-Nov-2016 08:51:00    NYC            01-Nov-2016 10:32:00
01-Nov-2016 09:05:00    BOS            01-Nov-2016 12:09:00

The result should be given as a table:

DayOfWk = {'Thu';'Tue';'Wed'};
  GroupCount = [5;6;4];
  numTrains = table(DayOfWk,GroupCount)
numTrains = 
    DayOfWk    GroupCount
    _______    __________
    'Thu'      5         
    'Tue'      6         
    'Wed'      4
