I have been using the interpolating worksheet in order to find unknown values for a recent project and it seems to be working perfectly. However, before I can publish I need to know that my values are reproducible. Since I don't know much about programming I was wondering if there is someone who knows exactly how OriginLab calculates unknown values in a scatter plot. I don't doubt that they are legitimate but I just need to know for practical reasons. I would greatly appreciate your help.
If you use the Analysis : Interpolate/Extrapolate dialog, Origin is performing linear interpolation. That is, given a sequence of distinct pairs of data (xi, yi), where i = 0, 1, , n-1. we are looking for the interpolated y at x by:
