changing the format of a date vector

Dear all,

I have the vector

A={

19/04/09'
  '17/05/09'
  '14/06/09'
  '12/7/2009'
  '9/8/2009'
  '6/9/2009'
  '4/10/2009'
  '1/11/2009'
  '29/11/09'
  '27/12/09'
  '31/01/10'
  '28/02/10'
  '28/03/10'
  '25/04/10'
  '23/05/10'
  '20/06/10'
  '18/07/10'
  '15/08/10'
  '12/9/2010'
  '10/10/2010'
  '7/11/2010'
  '5/12/2010'
  '2/1/2011'
  '30/01/11'
  '27/02/11'
  '27/03/11'
  '24/04/11'
  '22/05/11'
  '19/06/11'
  '17/07/11'
  '14/08/11'
  '11/9/2011'
  '9/10/2011'}

I want to have only the format dd/mm/yy. So instead of having '9/10/2011' i want to have '9/10/11'

thanks

Answer 1

[Azzi Abdelmalek]

B=cellstr(datestr(datenum(A,'dd/mm/yyyy'),'dd/mm/yy'))

Answer 2

[Oleg Komarov]

idx = cellfun('size',A,2) > 8;
A(idx) = cellstr(datestr(datenum(A(idx),'dd/mm/yyyy'),'dd/mm/yy'))

[Azzi Abdelmalek]

this does'nt work for 1/4/2009

Answer 3

[Walter Roberson]

idx = cellfun('size',A,2) > 8;
A(idx) = cellfun( @(S) S([1:end-4 end-1:end]), A(idx), 'Uniform', 0);
