27 Jul 2011 Surface Fitting using gridfit Model 2-d surfaces from scattered data Author: John D'Errico

Hi John,
I tried some smaller parameters (say 0.1 for smoothness), but then I get wave-like artifact pattern in my image.
What I am looking for is a combination: griddata in the inner part (so no smearing at all), and gridfit at the edge (where griddata produces NaN). Hence smearing is minimized. Can I achieve that by tuning parameters? Thank you very much!

22 Jul 2011 Surface Fitting using gridfit Model 2-d surfaces from scattered data Author: John D'Errico

Hi John, I have a set of 2d scattering data, and I want to have interpolation values at a regular (1:N,1:N) lattice. What parameters should I use to minimize the smoothing? (I need to iterate the interpolation for 50+ times, setting "smoothness"=1 for 50 times makes the resulting image very blur).
Thanks!
