Why am I getting "Undefined function or variable" when I use an exponential in the function?

My code worked for other functions, but as soon as I use the exponential function, I am getting an error saying that "I" is undefined, and I honestly have no idea why it's giving me an error only for the exponential function.
a = 0;
b = 1;
N = 10;
f = @(x) exp(-x);
h=(b-a)/N;
j = 0;
x=linspace(a,b,N);
for i = 1:N-1
j=j+f((2*i+1)/2)*x;
end
answer1 = sum(I)

There is no "I" variable in your code. Hence the error.

What does the exponential have to do with your problem of "I" not being defined?

I wonder if it is possible Nocholas has created a script of function named exp?
