mask = cellfun(@isempty, D0_txt(1:r_txt-1));
D0_txt2(mask) = {'0'};

Works for me, other than it coming out as a row vector by default:
D0_txt = cell(20,1);
D0_txt([3,7,13,19]) = {'10A'};
r_txt = 20;
mask = cellfun(@isempty, D0_txt(1:r_txt-1));
D0_txt2(mask) = {'0'};
>> D0_txt2
D0_txt2 =
1×18 cell array
'0' '0' [] '0' '0' '0' [] '0' '0' '0' '0' '0' [] '0' '0' '0' '0' '0'
Possibly your cells that look blank are not empty and hold blanks instead.
You might notice that the output includes [] . Those are at the positions where D0_txt was not empty. You did not define what the contents of D0_txt2 should be where D0_txt is not empty.
