MATLAB: How to combine two cell arrays into one cell array

Question

 >> Q{1}
 ans = 
    '4400002970000003533'
    '4400002970000003533'
    '4400002970000003535'
    '4400002970000003536'
    '4400002970000003533'
    '4400002970000003532'
    '4400002970000003537'
 >> 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?

Answer 1

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
