"Lookup table" with interpolation

splee · ‎05-04-2012

Hi,

I have an Excel chart which has x- and y- value (x is voltage, y is speed). I want to implement a lookup table in LabVIEW:

- store this x-y chart in VI

- and when user key in a x value, the VI should find a corresponding y value (interpolation is to be implemented).

Essentially this is a LUT with interpolation.

How can I do this? Any example?

Thank you..

Hi splee,

wow, there's a ready-to-use function in LabVIEW...

Best regards,

Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T

Side comment: You can eliminate the two bundle nodes by using "build cluster array".
