can convert date to another form?

hi, can convert x=('2005-04-20') into 2005,04,20

I wan to say that I got date from text using textscan i.e length of x=1

when I used datenum('2006-04-20','yyyy-mm-dd')

ans =

7.3279e+005
and when use
datenum('2006-04-19','yyyy-mm-dd')

ans =

7.3279e+005
it is not sensitive for small changes

but when used datenum(2006,04,19)

ans =

      732786
datenum(2006,04,20)

ans =

     datenum(2006,04,19)

ans =

      732786
it is perfect
 can got that?
thanks

It is just a display formatting issue:

format long

datenum('2006-04-19','yyyy-mm-dd')

ans = 732786

datenum('2006-04-20','yyyy-mm-dd')

ans = 732787

Hi,

it looks as if the datenum of your string gives a fractional number (no integer). This happens, if the time is not 00:00:00. You can check using

datevec(datenum('2006-04-20','yyyy-mm-dd'))

What do you get? Do you get

2006  4  20  0  0  0

or something like e.g.

2006  4  20  12 23 35

Which version of MATLAB are you using, btw.?
