In addition to Walter's suggestions, it may also be possible to take advantage of the roll-over behavior of the datetime constructor:
>> datetime(2016,11,1,(0:3:36)',0,0)
ans =
13×1 datetime array
01-Nov-2016 00:00:00
01-Nov-2016 03:00:00
01-Nov-2016 06:00:00
01-Nov-2016 09:00:00
01-Nov-2016 12:00:00
01-Nov-2016 15:00:00
01-Nov-2016 18:00:00
01-Nov-2016 21:00:00
02-Nov-2016 00:00:00
02-Nov-2016 03:00:00
02-Nov-2016 06:00:00
02-Nov-2016 09:00:00
02-Nov-2016 12:00:00

Don't create individual variables. Instead use the colon operator to create a vector.
N = datetime('now');
d = N:hours(3):(N+days(1));
% or
d = N + hours(0:3:24);
