This is what i have but it wont compute anything..
number = input('Enter a number here:');
function result = mySum(numbers)
numbers = num2str(number) - '0';
if length(numbers) == 0
result = 0;
else
result = numbers(end) + mySum(numbers(1:end - 1));
end
end

Hi Matt,
You have written function definition but missed to call the function 'mySum', that is why it is unable to compute anything.
You can refer to the following code snippet to achieve this
numbers=input('get a number');
numbers = num2str(numbers);
out=mySum(numbers)
function result = mySum(numbers)
result=0;
for i=1:length(numbers)
result=str2double(numbers(end))+mySum(numbers(1:end-1));
end
end
Hope this helps you!

% This program does not require any inbuilt functions.
function x = digit_sum(n)
x=0;
if n>0
x=mod(n,10)+digit_sum(floor(n./10));%recursive
end
