The length of x vector is 3 and you defined y vector the same vay but at the line 21 when i=4, you try to reach y(4), which is invalid because you already defined that y has 3 elements at the line 11. Check it.

ok, so I changed it to y=zeros(1,3), but I'm getting the same message, if I defined the index as i=1:3, shouldn't it stop at y(3)?

No, but at line 21, you still try to reach i+1, which makes 4 when i=3. The error arises from there.
