Reverse interpolation

Hi,

 

If anyone has worked or developed the logic for reverse interpolation, please guide me on that.

 

thanks,

PK

What is a reverse interpolation? If you have a data set you can insert a point, which is interpolating. I suppose the reverse would be going from points to a data set, so a curve fit?

Your term (Reverse Interpolation) is very poorly defined, so please explain in detail what you are trying to do or at least give a link to a website that describes the theory and algorithm. What kind of data do you have and what are you trying to get out of it.

You probably want extrapolation.  Either your point falls within your data set, or it falls outside and you need to extend the data either linearly or with a curve.  There are a lot of VIs that fit to a curve and then compute a point anywhere on the curve.

Or thresholding?

 

Interpolation: given a X, get a Y between values.

Or is it input prediction ?

You have a system output and try to reconstruct the input?
