datenum

[Carine Simon]

Hi,

I am using the function datenum written by Paul Kienzle (Copyright 2000) but I’ve got some trouble with it.

Indeed, when I type datenum(2000,1,1), I get 730485 whereas with Matlab, I get 730486.

More important, in the application I am using, I’ve got the following lines:

  da=clock;

  DayOfYear=datenum(0,da(2),da(3));

In Matlab as in Octave, the first line does work as it gives: da(2) = 12, da(3)=10.

Now, if as expected, DateOfYear=345 with Matlab, I get DateOfYear=-1 with Octave.

So, would you know where it comes from?

Thanks,

Carine.
