Function for Spline on Non Square Matrix
mpittarddisabled Jul 16, 2001 12:00 AM (in response to ValeryOchkov)The idea is great. However, I get the following error.

superres Jul 16, 2001 12:00 AM (in response to mpittarddisabled)That appears to be the correct behavior. The last element of M's first column (X) is 300 and the program sets the error code when x exceeds
max(X)

After searching for hours, the function GenInterSpline that youa re talking about is exactly what I need! However, I can't seem to get it, as it does not appear to be attached to your post. Can you send it?
Thanks!

AlexandreTrudel Jul 8, 2011 6:20 AM (in response to MikeArmstrong)Hi,
I am trying to interpolate a z value from a set of (x,y) data points with a cubicspline fit. I succeeded in doing this with a 3rd order polynomial regression, but I would like to compare the quality of the fit with a cubicspline fit. See attached for the data.
Thanks.
