>> Q{1}
ans =
'4400002970000003533'
'4400002970000003533'
'4400002970000003535'
'4400002970000003536'
'4400002970000003533'
'4400002970000003532'

>> Q{2}
ans =
'4400002890000146180'
'4400002890000146180'
'4400002970000000026'
I want to get a new cell:
'4400002970000003533'
'4400002970000003533'
'4400002970000003535'
'4400002970000003536'
'4400002970000003533'
'4400002970000003532'
'4400002970000003537'
'4400002890000146180'
'4400002890000146180'
'4400002970000000026'
I don't want to use the function cell2mat, because it is too slow for my program. Do you have any good ideas?

To get the result cell array ‘R’, for instance, vertically concatanate ‘Q{1}’ and ‘Q{2}’:
Q{1} = ['4400002970000003533'
'4400002970000003533'
'4400002970000003535'
'4400002970000003536'
'4400002970000003533'
'4400002970000003532'
'4400002970000003537'];
Q{2} = ['4400002890000146180'
'4400002890000146180'
'4400002970000000026'];
R = {[Q{1}; Q{2}]};
celldisp(R) % Display Result

@Adam — The vertcat function is definitely the way to go!
You’re certainly correct on your observation — in more Questions that I care to count, the instance in the question may have little bearing on actual issue!

Maybe this little function could be useful:
function [celltot] = juntar_cells(cell1, cell2)
celltot = cell1;
for ll_cell2 = 1:length(cell2)
celltot{end + 1} = cell2{ll_cell2};
end
end
