first derivatives

[Paul_Knight_Lockheed_Mart]

Is there a equalivent LabWindows/CVI function for the LabView NI_AALPro.lvlib:Derivative x(t).vi?  I notice that it ends up at a Call Library Function "Derivatives85" in the lvanlys.dll.

I need to find the transition point where the slope goes vertical in the attach graph.

Try the advanced analysis library PeakDetector function.  It will also find second derivatives for you.

Thanks, that solved the issue.

Hi Paul,

The "solution" to your question is what menchar provided, not your "thank you" message.

For the sake of healthy forum statistics mark the "answer" that solves your problem, not your own messages.

Take care, 😉

Thanks for pointing that out  

I had noticed what had happened, it was kind of funny actually.
