error while executing datenum
in [Matlab]
|
From: guyz Smarty on 27 Jul 2010 15:39 Hi all, I don't know if it is too basic problem or not. but it is really annoying. I am trying to execute following command: datenum('02 01 2008','dd mm yyyy') But unfortunately, I get following error message: >> datenum('02 01 2008','dd mm yyyy') ??? Error using ==> datenum at 182 DATENUM failed. Caused by: Error using ==> dtstr2dtnummx Failed on converting date string to date number. Ans now comes the strange thing. If I run the same command again, I get the correct result this time. But, I get the error message again if I try to run the same command. What I mean to say is that the command runs for me (or I get the correct result) every alternate times. I will paste the command window lines here to make things clearer. ===================================== >> datenum('02 01 2008','dd mm yyyy') ans = 733409 >> datenum('02 01 2008','dd mm yyyy') ??? Error using ==> datenum at 182 DATENUM failed. Caused by: Error using ==> dtstr2dtnummx Failed on converting date string to date number. >> datenum('02 01 2008','dd mm yyyy') ans = 733409 >> datenum('02 01 2008','dd mm yyyy') ??? Error using ==> datenum at 182 DATENUM failed. Caused by: Error using ==> dtstr2dtnummx Failed on converting date string to date number. >> datenum('02 01 2008','dd mm yyyy') ans = 733409 ===================================== Any help would be appreciated. Thanks.

But as I mentioned I couldn't reproduce this behaviour. If the OP can post the whole code being executed before he gets the error it would be useful, so that I can compare with my routine too. Oleg
