add blank spaces in cell array

I have the following array

ar=

         0     1     0     0     0     0     0     0     0     0
         0     0     0     3     0     0     0     0     0     0
         0     0     0     0     0     0     2     0     0     0
         0     0     0     0     0     0     0     0     3     0
         4     0     0     0     0     0     0     0     0     0

And I would like to create a 5x1 cell array C like this one:

C =

5×1 cell array

    {'          0           1           0           0           0           0           0           0           0           0'}
    {'          0           0           0           3           0           0           0           0           0           0'}
    {'          0           0           0           0           0           0           2           0           0           0'}
    {'          0           0           0           0           0           0           0           0           3           0'}
    {'          4           0           0           0           0           0           0           0           0           0'}

That is with 10 blank spaces at the beginning of each row. I tried this:

   fmt=repmat(' % 11.1i',1,10);
   fmt=['          ' fmt4(2:end) '\n'];
   rew=num2str(ar,fmt4)
   tes=num2cell(ar)
   C = cellfun(@cell2mat,num2cell(tes,2),'un',0)

And I get this:

C =

5×1 cell array

    {'0           1           0           0           0           0           0           0           0           0'}
    {'0           0           0           3           0           0           0           0           0           0'}
    {'0           0           0           0           0           0           2           0           0           0'}
    {'0           0           0           0           0           0           0           0           3           0'}
    {'4           0           0           0           0           0           0           0           0           0'}

Is there a way to add the blank spaces in cell array C?

What does "That is with 10 blank spaces at the beginning of each row" mean for values with more than 1 digit?

Answer 1

[Jan]

ar = [0,1,0,0,0,0,0,0,0,0; ...
      0,0,0,3,0,0,0,0,0,0; ...
      0,0,0,0,0,0,2,0,0,0; ...
      0,0,0,0,0,0,0,0,3,0; ...
      4,0,0,0,0,0,0,0,0,0];

fmt = repmat('%11d', 1, size(ar,2));
% Either:
C   = sprintfc(fmt, ar);   % Unfortunately not documented
% Or:
D   = compose(fmt, ar)     % Working since R2016b
