21 Nov 2012	Surface Fitting using gridfit Model 2-d surfaces from scattered data Author: John D'Errico	Is it possible to extend this idea to fit 3d volume to scattered data, and in general, to higher dimensions? The only limitation I can see is matrix size.

01 Sep 2011	BrokenStickRegression A line consisting of connected straight sections is fitted to a cloud of data points. Author: Peter Nave	Really well written code, exactly what I was looking for. I want to specify only one breakpoint in between the end points -- something this code doesn't allow. But I guess it's an easy modification that I can make if needed.

11 Feb 2013	Surface Fitting using gridfit Model 2-d surfaces from scattered data	Roman Voronov	Exactly what I was looking for, the help could start with a simpler example: [X,Y] = meshgrid(1:5); Zsmooth = gridfit(X,Y,A,1:5,1:5,'smooth',10) Zsmooth = 0.9638 1.9517 2.9512 3.9517 4.9638 1.9517 2.8162 3.7338 4.8162 5.9517 2.9512 3.7338 4.5266 5.7338 6.9512 3.9517 4.8162 5.7338 6.8162 7.9517 4.9638 5.9517 6.9512 7.9517 8.9638	2
06 Feb 2013	Surface Fitting using gridfit Model 2-d surfaces from scattered data	John D'Errico	Andrew - It sounds like your goal is to reproduce the local shape of your surface over a region that lies inside the bounds of your data. Gridfit can do this, if you are willing to expand that grid so that it fully contains the data. Simply add some nodes that extend to the boundaries of your data in both x and y. The nodes used by gridfit need not be equally spaced, so this should not be a problem, but to retain the essential shape of the surface, you may need to add a few such nodes in each direction. Once the fit is obtained, then you can always extract only that portion of the surface that you wish to retain. If this is not what you are looking for, then feel free to contact me directly, perhaps with some data so that I can better understand your problem.	Comment only
05 Feb 2013	Surface Fitting using gridfit Model 2-d surfaces from scattered data	Andrew	This is an amazing program. I do have one question. I have a scattered grid of latitude(Y) and longitude(X) coordinates corresponding to brightness(Z) values. I've been using GRIDDATA to interpolate to a new grid that is not scattered and within a smaller range of latitude and longitude values, but GRIDDATA smooths the data so much that it becomes useless. I understand that GRIDFIT is not an interpolant, and from my reading of the help, it does not seem that it was meant to be used in this fashion, but I just want to make sure.	Comment only
21 Nov 2012	Surface Fitting using gridfit Model 2-d surfaces from scattered data	John D'Errico	Collin - What you wish is essentially a 3-d version of gridfit, that could use time as the third dimension. Sorry, but perhaps one day...	Comment only
