MATLAB: How to find and replace the content of an array

cellfindreplace

Hi guys. Sorry to bother you again, but I am new at Matlab.
I have this timestamp array:
'03/07/2019'
'03/07/2019 00:30:00'
'03/07/2019 01:00:00'
'03/07/2019 01:30:00'
'03/07/2019 02:00:00'
'03/07/2019 02:30:00'
And it goes for 10 days (480 values). The first cell of each day is like '03/07/2019', time is missing. I need to find this kind of cell
and add '00:00:00' to the cell content. So, the first cell should be '03/07/2019 00:00;00' instead of '03/07/2019'.
I applied the function cellfun. The length of the desirable cells is 10. I know I have to find the content of these cells and replace it,
but I am writing a loop. I wonder if there is an easier way to do that.
Thank you for your support!

% sometimestamp = {'03/07/2019' '03/07/2019 00:30:00'};
l = cellfun(@length,sometimestamp);
% or
% l = strlength(sometimestamp);
sometimestamp(l==10) = cellfun(@(x)[x ' 00:00:00'],sometimestamp(l==10),'UniformOutput',false);
