I want to add each element of the ans :

i.e., >> 3+6+0+3+3+6+3

ans =

Lots of ways...just a couple--

>> sum(str2num(num2str(789*4567).'))
ans =
  24
>> >> sum(sscanf(num2str(789*4567),'%1d'))
ans =
  24
>>

Try this:

theNumber = 3603363
theString = num2str(theNumber)
theSum = sum(theString - '0')

(I hope I didn't just do your homework.)
