comment Can you import/include a header file in Mathematica?
While writing a package is definetly the best way, you can just stick some definitions into an .m file and import that from all other notebooks.

comment Implementation of smoothing splines function
@Andy Well I read your answer in detail as I was trying to generate a 2D Bspline basis (in this Q). But I have not figured it out yet as I only get a symmetric fit...

Hmm, where are n kmin and kmax used inside of SplineModel?

comment 2D smoothing spline interpolation
@RahulNarain Indeed, but the surface also goes through every point, which if there is noise is not desirable.

comment 2D smoothing spline interpolation
@ybeltukov Yes, GaussianFilter (or any other smoothing algorithm; perhaps a wavelet transform) + Spline interpolation would work as well.

comment 2D smoothing spline interpolation
Hi! Perhaps the question or the example code was a bit misleading. I need to obtain a differentiable interpolated and smoothed function from the data. In the test case it should be as close as possible to the original.

Fixing the plotrange might give an even better animation. Still +1

comment Fitting a plane from a set of (x,y,z) values with uncertainties on 3 variables
The weights are for data points see here. As for posting code, we used to have a FAQ, but I can't seem to find it. @belisarius will know.

I guess you would like to use the measured errors as weights for LinearModelFit?
