...then again...maybe not!
Somewhat simplified for purposes of this post I wish to implement the floowing within AF.
x(k) = x + x(k-1)
where x is a PI Point. The function should re-evaluate when a new value of x appears. This said a new value of x may be identical to the previous value of x!
As written this is a simple summation. In reality the expression is more complex. However the issue remains the same. How can I implement this in AF? If indeed I can. I've tried Formulae, Analysis, Formulae + Analysis but in every case I end up with a circular reference. Then tried with a PI Point for the x(k) but still not resolved.
