Hello everybody, I have a problem. In a LabView VI I calculated a spline function with the 1d-spline-interpolation during an experiment: http://zone.ni.com/reference/en-XX/help/371361E-01/gmath/spline_interpolation_1d/ In "X" I have set 4 points - index 109, 288, 421, 534 - with which I calculate 640 points in all (including the 4; 640 set with "Xi") and all works fine.The problem is, the base points were slightly wrong. Now, the correct 4 point index are 102,281,425,540. I cannot repeat the experiment, but the data is generally ok - I just have to recalculate the spline in DIAdem, which leads me to the problem - how? Specifically, how do I get the points 1-101 and 541-640? How do I make sure it is the same math? Apparently LabView extrapolates somehow and I dont understand how. Just to clarify, I have the 4 values in DIAdem and need to calculate it, as LabView would have done it. The calculation by LabView has always been satisfying and worked well. Thanks!
