Hi All, What is the best method to obtain the highest speed for the code in attached formula node?

A few simple suggestions: Use complex math to do the input processing. x2 and /2 should be done using scale by powers of two because it is especially easy in binary. I am not sure if the compound multiply really constant folds the (0.0005x pi x pi), so I would take that out. I would recommend to save the VI so the controls are in view. it is useful if the controls have some default values.

I hope my colleague @altenbach will forgive me for "poaching" on his pleasure of turning scripts from Visual Basic code into LabVIEW. Thank you to the Original Poster for providing the reference. Rather than tackle the function for MCoil, I did the "inner function" it calls, "mut" (which I named "Mutual Inductance", following the principle that when you are dealing with LabVIEW, there is no sense in obscuring things by choosing single letters to represent variables). You can see that I added the Error Line (always a good idea), that the "loop" is now a While Loop with a "Run-until-done" condition, all the temporary variables are initialized before being brought into the While Loop as Shift Registers (because they are modified within the loop), and the final result is calculated when the loop exits.

Hi,

Attached the .vi. It works correctly, I have verified and it is what I was searching for. No need others.

Thank you very much for supporting me.

Best regards,

Mal
