date = ['9/12/2010'; '9/12/2010'; '9/12/2010'];
time = ['19:01:43.67'; '19:02:43.67'; '19:03:43.67'];
spaces = [' '; ' '; ' '];

%This works but I have a bunch of really big files so I'd like to
%vectorize the operation
for i=1:3
    dateTime(1,:) = [date(i:i,:) ' ' time(i:i,:)]
end

dateTime2(1:3,:) = [date(1:3,:) spaces time(1:3,:)]
