My code was in a. But that isn't what you did. What's the Bottom Line? Perhaps you are trying to perform interpolation on the surface of a sphere? You may receive emails, depending on your notification preferences.

I have a colleague here at The MathWorks who has a strong background in Medical Imaging and I will discuss this enhancement request with him to gain some insight into how we can better support this workflow.

To evaluate using natural neighbor interpolation we do the following:. Answer by Walter Roberson Walter Roberson view profile. Bruno Rodriguez Bruno Rodriguez view profile. The OA package generates qfields on a constant depth: The large performance gains that Mike observed are triscattredinterp unique to the computational geometry classes in the context of problem size and level of iteration.

To facilitate this type of interpolation in other scripts, two new generic functions are coded: Bruno Rodriguez view profile.

DelaunayTri is for triangulating data and querying that triangulation. However the faces are "inside" the sphere.

TriScatteredInterp not interpolating as expected? But the problem is that I cannot reuse this interpolation F to run over the same x,y points with a different set of z-data, because the other z-data defined over the same x,y will not have the redundant points removed.

TriScatteredInterp not interpolating as expected? - MATLAB Answers - MATLAB Central

Seems to defeat some of the improvment over delaunay. In effect, all your data is outside the convex hull defined by the mesh. Opportunities for recent engineering grads. V takes triscatferedinterp longer than creating F with TriScatteredInterp. However, for every x-coord, the range of heights I need interpolated differs, so I would not have a rectangular array Kriging, radial basis functions, … Basically i would like to be able to do what Surfer does, only inside matlab.

But hey, it's a vacation, forget it. Visit the Trac open source project at http: An Error Occurred Unable to complete the action because of changes made to the page. If so, I take it I need to limit my range of Z. There are various ways to connect the dots to build the triangulation, but the Delaunay algorithm is the best because it favors connecting points that are in close proximity to triscattereinterp other. For example, when eliminating duplicates you may wish to average the corresponding Z values.

Most of your z are not in the same range as your height so the interpolant is applying its default extrapolation of putting in nan. Is there a way around?

Choose a web site to get translated content where available and see local events and offers. So if I understand correctly, it is overriding those "z" that DO lie within the range of heights? I suggest you review some recent literature tdiscatteredinterp deals with a comparison of the various methods in the area of scattered data interpolation.

If you pass in vectors of equal length then only the points you indicate will be interpolated. In some cases the data is acquired along spiral or radial paths in k-space and gridding is used to interpolate the data onto a Cartesian grid so a fast Fourier transform can be used to obtain an image. For more information on this feature and the new computational geometry features shipped in Ra check out the overview videoand Delaunay triangulation demoor follow friscatteredinterp links to the documentation TriRepDelaunayTriTriScatteredInterp.

Is there an interpolation routine where I can force it to only interpolate from points within a specified radius? For triscattredinterp, we could compute the total rainfall at longitude, latitude for years, etc, and likewise we could do the triscatteredinerp for total snowfall.
