Iterative Functions in 1.3

Trying to understand the new iterative functions in 1.3.
Can somebody give an example of how it works? How would you achieve feedback or repeating cycles? Does a “pass” mean any change of the output value or is there a time value involved? What is the initial value of “V”?

Iterative functions: For the functions below which use the letter “V”, V is the function’s result value from the previous pass. This allows for feedback and repeating cycles.

  • C(S-V)
    Subtract V from SOURCE and multiply it with CONTROLLER
  • C(V+S)
    Add V to SOURCE and multiply it with CONTROLLER
  • CV+S
    Multiply V with CONTROLLER and add to SOURCE
  • (C+1)V+S
    Add 1 to CONTROLLER and multiply with V, then add to SOURCE
  • V+C(V+S)
    Add V to SOURCE and multiply with CONTROLLER, then add to V
  • C|V|+S
    Take absolute value of V and multiply with CONTROLLER, then add to S
