merge multiply cell together

Hi guys: I have two cells as follow:

C1={[1:10], [2; 4; 6], []};
C2={[],[],[2;3];

These two cell has same length and opposite void and valid elements, I want to put the elements in one cell , let's say C3={[1:10], [2; 4; 6],2;3]} How can I do that? Thank you very much!

C3=horzcat(C1,C2);
C3(cellfun('isempty',C3))=[]

Equivalent, but perhaps slightly faster for huge cells:

index = cellfun('isempty', C1);
C3 = cat(2, C1(~index), C2(index));
