Combine date and duration into single datetime column

22 views (last 30 days)
Hello!
I have a vector containing the data in a datetime format (MM/dd/uuuu)and the vector containing the hours of the days in duration format(hh:mm:ss)
I want to combine the two vectors in order to get a single datetime vector having date and hour togheter.
I tried this code but it seems that is not working:
new_datetime=date+hour;

Add them —
DT = datetime(repmat([2018 01 01], 5, 1))
DT = 5×1 datetime array
01-Jan-2018 01-Jan-2018 01-Jan-2018 01-Jan-2018 01-Jan-2018
DU = duration('00:00:00') + 5*minutes(0:4)'
DU = 5×1 duration array
00:00:00 00:05:00 00:10:00 00:15:00 00:20:00
Combined = DT + DU
Combined = 5×1 datetime array
01-Jan-2018 00:00:00 01-Jan-2018 00:05:00 01-Jan-2018 00:10:00 01-Jan-2018 00:15:00 01-Jan-2018 00:20:00

I really don't know how this is possible. I simply exported the two columns of the table and they have been automatically merged... hence, I will use this datetime in table "T" for my work.
Neverthless, your answer should have worked and I'm gonna accept it.
Thank you for your patience!
