    '4400002970000003533'    '8500000840000006008'

csvwrite('s1.csv',S{1}); but when i open the file , the result is like this 4,4,0,0,0,0,2,9,7,0,0,0,0,0,0,3,5,3,3,8,5,0,0,0,0,0,1,9,0,0,0,0,0,1,3,0,9,3 4,4,0,0,0,0,2,9,7,0,0,0,0,0,0,3,5,3,3,8,5,0,0,0,0,0,1,9,0,0,0,0,0,4,5,5,0,1 4,4,0,0,0,0,2,9,7,0,0,0,0,0,0,3,5,3,3,8,5,0,0,0,0,0,8,4,0,0,0,0,0,0,5,6,6,0 4,4,0,0,0,0,2,9,7,0,0,0,0,0,0,3,5,3,3,8,5,0,0,0,0,0,8,4,0,0,0,0,0,0,6,0,0,8 do you konw why? can you help me? thanks

Remember that your strings are just arrays of characters. So when you export the array to file using csvwrite, a comma will be inserted between each element in the array - so a comma between each character.

You may want to consider an alternative method to export cell array data to a text file. From this example, you could do

 % open the file
 fid = fopen('s1.csv','wt+');

 if fid>0

     % write each row to file
     V = S{1};     % assumes that V is a cell array
     for k=1:size(V,1)
         fprintf(fid,'%s,%s\n',V{k,:});
     end

     fclose(fid);

 end

Now, when you open the s1.csv file, you will see

 4400002970000003533,8500000190000013093
 4400002970000003533,8500000190000045501
 4400002970000003533,8500000840000005660
 4400002970000003533,8500000840000006008

which is probably what you would like.

Read the documentation... Haha

"csvwrite does not accept cell arrays for the input matrix. To export cell arrays to a text file, use low-level functions such as PRINTF."

Using cell arrays will result in every character being split
