The 'InputFormat' and 'Format' name-value pairs are not the same. You need to specify them separately —

aaa=datetime(dataa,"InputFormat", "dd/MM/yyyy", 'Format','dd/MM/yyyy')

load('matlab_data.mat')
% whos
textdata = A.textdata

textdata = 5434×1 cell array
    {'01/01/2008'}
    {'02/01/2008'}
    {'03/01/2008'}
    {'04/01/2008'}
    {'05/01/2008'}
    {'06/01/2008'}
    {'07/01/2008'}
    {'08/01/2008'}
    {'09/01/2008'}
    {'10/01/2008'}
    {'11/01/2008'}
    {'12/01/2008'}
    {'13/01/2008'}
    {'14/01/2008'}
    {'15/01/2008'}
    {'16/01/2008'}
    {'17/01/2008'}
    {'18/01/2008'}
    {'19/01/2008'}
    {'20/01/2008'}
    {'21/01/2008'}
    {'22/01/2008'}
    {'23/01/2008'}
    {'24/01/2008'}
    {'25/01/2008'}
    {'26/01/2008'}
    {'27/01/2008'}
    {'28/01/2008'}
    {'29/01/2008'}
    {'30/01/2008'}

aaa = datetime(textdata,"InputFormat", "dd/MM/yyyy", 'Format','dd/MM/yyyy')

aaa = 5434×1 datetime array
   01/01/2008
   02/01/2008
   03/01/2008
   04/01/2008

   06/01/2008
   07/01/2008
   08/01/2008
   09/01/2008
   10/01/2008
   11/01/2008
   12/01/2008
   13/01/2008
   14/01/2008
   15/01/2008
   16/01/2008
   17/01/2008
   18/01/2008
   19/01/2008
   20/01/2008
   21/01/2008
   22/01/2008
   23/01/2008
   24/01/2008
   25/01/2008
   26/01/2008
   27/01/2008
   28/01/2008
   29/01/2008
   30/01/2008

% load('matlab_aaa.mat')
% whos

I am not certain what to do with the other .mat file.
