Creating cell array of strings in a loop

Hi all,
I have a few lines as such:
timeStrings = cell(1,entries_per_variable);
for o = 1:1:entries_per_variable
timeStrings{o,1} = [num2str(TimeValue(3,o),'%02i'),'/', num2str(TimeValue(2,o),'%02i'),'/', num2str(TimeValue(1,o),'%04i'),...
' ',num2str(TimeValue(4,o),'%02i'),':',num2str(TimeValue(5,o),'%02i'),':',num2str(TimeValue(6,o),'%02i')]; %this be a column vector
end
It basically converts some values in TimeValue to strings, adds some spaces and slashes using the [] string catenation method and puts them in a new cell array.
I'm running out of memory less than 50 entries in! As you can see the memory is preallocated so I can't fathom why.
Best regards,
Craig B

... you pre-allocate a 1xN array, but intend to fill a Nx1 array, ending up filling a NxN array ... (This should not give you memory problems though)
I also suggest you take a look at SPRINTF.
