I'm trying to make more sense of recursive code as I have only very recently started using matlab. I was wondering how I would go about finding the sum of all real numbers up to x using recursive code, I have done it using if / for / while loops however after trying to self teach myself I would expect to go about this by:
function y = sum(x)
if x > 0
y = x * (x+1) / 2
end
elseif x <= 0
y = 'does not exist'
end
end
disp(y)
I understand that I am probably wrong, in which case how would I go better about this task. Any help would be appreciated.

You can edit the code to fix it you know. So go ahead and add the end.
How are you calling this? What is the initial value of x you're using? I assume the x are all integers, right? Is x a scalar or vector? And you have a finite number of them. Because the sum of all real numbers is infinite.

function x = t_sum(n)
x=1;
if n>1
x=n+t_sum(n-1);%recursive
end
