num = input('enter your student number here : ');
NumChar = num2str (num);
MySum = 0;
for i1 = 1:numel (NumChar)
MySum = MySum + str2double (NumChar(i1));
fprintf ('Sum of the numbers is %d', MySum);

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

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
