MATLAB: Calculating the difference (in days) between successive dates

Question

Dear all,

I have the following sequence of dates

    dd={'2-11-2008'     '30-11-2008'    '28-12-2008'    '25-01-2009' '22-02-2009'   '22-03-2009'    '19-04-2009'    '17-05-2009'    '14-06-2009}';

Is there any code that could calculate the difference (in days) between two successive dates in dd?

To be more specific, first the difference '30-11-2008'- '2-11-2008' Then the difference '28-12-2008' -'30-11-2008' Then '25-01-2009'-'28-12-2008' and so forth…. Probably a loop would be a good choice as dd contains many elements in my case

thanks

Answer 1

dd={'2-11-2008'     '30-11-2008'    '28-12-2008'    '25-01-2009' '22-02-2009'   '22-03-2009'    '19-04-2009'    '17-05-2009'    '14-06-2009'};
out = diff(datenum(dd,'dd-mm-yyyy'))
