[Abdolkarim Mohammadi]

num = input('enter your student number here : ');
NumChar = num2str (num);
MySum = 0;
for i1 = 1:numel (NumChar)
    MySum = MySum + str2double (NumChar(i1));

Does your function work for student number 12345678901234567890? Since it consists of the digits 0 through 9 twice each, the sum should be 90.

[Abdolkarim Mohammadi]

You are right. This code does not work for that large numbers that do not fit into double. Stephen's answer is the correct one.

The MATLAB way:

>> str = input('enter your student number here: ','s');
enter your student number here: 20758562
>> num = sum(str-'0')
num =  35
