LabVIEW
Pass array to Eval Formula Node (any chance to avoid this?)
Solved!
Sorry about the "multiply vs add" compound node confusion. I forgot to set the mode to multiply after placing it. 😉
Some additional comments:
- multiplication is commutative, so the multiplication with Fm should be done once outside the loop. Use my code directly, but change the mode of the compound node from "add" to "multiply", of course.
- The "zero" diagram constant should be DBL to avoid coercion (just enter 0.0 to turn it orange)
- If you make the function an enum instead of a ring, the case structure will show the item name, thus avoiding coding mistakes.
- Why do you have the front panel maximized to the screen? There is not really much on it. This gives me tunnel vision! 😄
Indeed. altenbach likes to make things easy on people. 
Tip: You can use the Ramp Pattern VI to create your time values rather than the loop in the bottom left.

In addition, we can do all multiplications on the scalars, thus making ~N times fewer operations before the loop. 🙂
Also, the sampling frequency should probably be DBL. Why restrict it to integers?
Here's how if would look like using "ramp pattern".
Depending on what you want, you should round up or down to get N.
(It is possible that the ramp pattern looks slightly different in LabVIEW 7.1).
