Printing lines of text from cell array?

Suppose I had a simple cell array :

D = {[1 2 3],[4 5 6 7 8 9],[10 11 12 13 14 15 16 17 18 19 20]}

How could I print each line (one cell per line) into the command window, one character at a time?

I know fprintf('\n') needs to be used to jump to the next line.

Appreciate any advice.

One approach:

D = {[1 2 3],[4 5 6 7 8 9],[10 11 12 13 14 15 16 17 18 19 20]}

for k = 1:numel(D)
    fprintf(1, [repmat('%d ',1,numel(D{k})) '\n'],D{k})
end

Would that output one character at a time? I tried it but couldn't tell. I may have to use pause somewhere.

It outputs a line at a time.

To output one character at a time, a second loop that loops through each line would be necessary:

D = {[1 2 3],[4 5 6 7 8 9],[10 11 12 13 14 15 16 17 18 19 20]}
for k1 = 1:numel(D)
    for k2 = 1:numel(D{k1})
        fprintf(1, '%d ',D{k1}(1,k2))
    end
    fprintf('\n')
end
