Problem with datestr e datenum

Hello!

I have a code that read a xls file and get a colum of dates:

data_even ---- 60x1 cell

    ' 31/10/2012'
    ' 31/10/2012'
    ' 01/11/2012'
    ' 01/11/2012'  .....

I want to compare some dates, so i need to convert it using datenum() and when i return to string for my conference i see a diferece way to show the date, take a look:

>> x = datenum(data_even)  

         13608
         13608
        734879
        734879

>> y = datestr(x,'dd/mm/yyyy')

       03/04/0037
       03/04/0037
       11/01/2012
       11/01/2012

Someone help me please.

I try to convert the data_even vector to string from a cell and here the result:

>> datestr(data_even,'dd/mm/yyyy')

   03/04/0037
   03/04/0037
   11/01/2012
   11/01/2012

the same problem occurs!

>> data_even = {' 31/10/2012'
                ' 31/10/2012'
                ' 01/11/2012'
                ' 01/11/2012'};

>> x = datenum(data_even,'dd/mm/yyyy')

x =

        735173
        735173
        735174
        735174

>> y = datestr(x,'dd/mm/yyyy')

y =

31/10/2012
31/10/2012
01/11/2012
01/11/2012
