Printing lines of text from cell array?

1 view (last 30 days)
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
.

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
.
