I have time in hours from 0-72 hours (i.e. 0, 1, 2, 3,..., 72). i.e. a = 0:72;
I would like to convert this hours into datestr with 'yyyy-MM-dd hh:mm:ss' format.
I know initial yyyy-MM-dd i.e. 2012-04-24.
So how can i set my output in 'yyyy-MM-dd hh:mm:ss' format?
I want o/p to be like;
2012-04-24 00:00:00, 2012-04-24 01:00:00, ...., 2012-04-25 00:00:00, 2012-04-25 01:00:00, ...., 2012-04-26 00:00:00, 2012-04-26 01:00:00
date should change with each 24 hours.
Any help will be greatly appriciated.

dtm = datetime(2012,4,24,'Format','yyyy-MM-dd HH:mm:ss') + hours(0:72).'
dtm = 73×1 datetime array
2012-04-24 00:00:00 2012-04-24 01:00:00 2012-04-24 02:00:00 2012-04-24 03:00:00 2012-04-24 04:00:00 2012-04-24 05:00:00 2012-04-24 06:00:00 2012-04-24 07:00:00 2012-04-24 08:00:00 2012-04-24 09:00:00 2012-04-24 10:00:00 2012-04-24 11:00:00 2012-04-24 12:00:00 2012-04-24 13:00:00 2012-04-24 14:00:00 2012-04-24 15:00:00 2012-04-24 16:00:00 2012-04-24 17:00:00 2012-04-24 18:00:00 2012-04-24 19:00:00 2012-04-24 20:00:00 2012-04-24 21:00:00 2012-04-24 22:00:00 2012-04-24 23:00:00 2012-04-25 00:00:00 2012-04-25 01:00:00 2012-04-25 02:00:00 2012-04-25 03:00:00 2012-04-25 04:00:00 2012-04-25 05:00:00

I want to put xticklabels.
If you're plotting using this datetime data as one of the inputs in your call to plot, the tick labels will automatically be generated from the plotted datetime array. You don't need to convert to a string array in this case.
v = 0:10;
x = datetime('today') + days(v);
y = v.^2;
plot(x, y)
