You are analyzing a train timetable (you have some time to kill since you just missed your train!) What is the average daily trip duration?

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 a duration variable:

Dur = [duration(3,9,05);duration(2,55,15);duration(3,0,24)]
Dur = 
3×1 duration array
 03:09:05
 02:55:15
 03:00:24

Feature Tip: R2016b introduces timetables with related functions which may be helpful. To learn more see MATLAB Timetables.
