date and time convert in number

Hi

I have :

    % 
date vector:
a=['1.1.2010';'2.2.2010';'2.5.2010'...]
 time vector:
b=['1.2.58';'2.5.52';'4.6.30'.....]
date_time=[a b]

i transform the vector from cell to array with cell2mat and i get

    % ab=1.1.20102.2.58
         2.2.20102.5.52
         2.5.20104.6.30

how could i isert white space between date and time to be able to use datenum?

thank you

Please note, that this definition will fail as soon as any day or month has more than 1 digit:

a = ['1.1.2010'; '2.12.2010'; '2.5.2010'];  % ERROR! Different lengths!

For storing string of different size, a cell string is reuquired.

a = ['1.1.2010'; '2.2.2010'; '2.5.2010'];
b = ['1.2.58'; '2.5.52'; '4.6.30'];
c = strcat(cellstr(a), {' '}, cellstr(b));

%date vector:
a={'1.1.2010';'2.2.2010';'2.5.2010'}
% time vector:
b={'1.2.58';'2.5.52';'4.6.30'}
date_time=[a b]

hi!

but you could not use datenum(date_time)!
