Attempted to access A(2); index out of bounds because numel(A)=1

This is the for loop I am trying to use but I keep getting that error message saying

Error, Attempted to access A(2); index out of bounds because numel(A)=1.

How to fix this?

x = 0
for i=1:5
    z = x + A(i)*exp(j*phi(i))
    x = x + z
end

numel means the number of elements in a given array/ matrix. You would have given A as a single number, therefore numel(A) = 1. You can access it by A(1). How you can get A(2)? when there is no A(2)?

Any ways in your code above, you have not shown A. According to your loop, A must have 5 elements.
