Produce a Date vector starting with a desired date

Hi all,

I want to generate a date vector that starts at, say '01-Jan-2001 00:00:00' and skips by hour all the way up to '31-Dec-2031 23:00:00'.

I tried this:

Date = datevec('01-Jan-2011 00:00:00','dd-mmm-yyyy  hh:mm:ss', 
       '31-12-2031 23:00:00');

 But I don't think that's the way.

Any suggestions??

Any attempt to help is appreciated,

a = datenum({'01-Jan-2011 00:00:00';'31-Dec-2031 23:00:00'});
Out = datevec(a(1):1/24:a(2));

The output is the same as a(2) :/

Instead of 1/24 you have to put nH.

The problem with my script is not the generation of the numerical dates, which IMHO are more secure with:

datenummx([o*dtv(1), o, o, (1:nH).', z,z])

The bottleneck is in datestr.

What andrei meant to write was this:

a = datenum({'01-Jan-2011 00:00:00';'31-Dec-2031 23:00:00'});

datevec(a(1):1/24:a(2));

I actually make the make mistake a lot too...

make the SAME mistake a lot too...

Ohhhh man it is working perfectly now, and quite fast as well.

Thanks a lot for the help guys

very large thank you Teja , again my typo ... corrected

My version had a small bug (nevertheless it did differentiate between 30,31 and lap years) but Andrei's version is really the best.

To convert to strings (takes time):

datestr(Out,0)
