numbers12 ={3,6,12,1,1,3,26,20}
lettter=cellfun(@num2str,numbers12,'un',0)

As the question gives a numeric vector, then arrayfun will also work:

>> X = [3,6,12,1,1,3,26,20];
>> arrayfun(@num2str,X,'un',0)
ans = 
  '3'    '6'    '12'    '1'    '1'    '3'    '26'    '20'

Hi , You can use num2str command. e.g. numbers12 = num2str(numbers12 ) so your number array in char Hope this helps you.
