making the string into a matrix

N=length(str);
   count=1;
   for k=1:N
       m=str2double(str(k));
       if isnan(m)==0
           str(count)=k;
           count=count+1;
           numbers = cell2mat(sscanf((str),'k'))
       disp(m)
       end
   end

this is currently the code I have "str" is the number inputted by the user, however my code isn't working. If the user were to input: 1234509876 then I would want the outcome to be numbers=[1,2,3,4,5,0,9,8,7,6]; what can I do?

How do you intend to hand the case where the user asks for 0 as the first entry? For example if the user asks for 007 then how do you intend to tell the difference compared to if they had just asked for 7 ?

    n =  1234509876 ;
   iwant = sscanf( sprintf( '%u', n ), '%1d' )'
