Tarek, that just means you haven't compiled the library. @see kdtree_build

The SVN now contains the corrections pointed out by Levi and Jeremy.

Sorry for the butchered english in my last message ^_^

Be advised.. The library has been subject to large updates and it's in Beta. It's much faster and it offers a matlab class wrapper. The updated library can be found at the following URL:
(Includes 64bit binaries for OSX and WIN7)

@Jose, yah the tree is static.. sorry
@Bryan, that's a good question :) I am working on the library these days, I will try to answer it.

I have same problem mentioned by Jon. I am using R2014a.

Any help, pls

18 Aug 2014 kd-tree for matlab A kd-tree mex lib which allows for nearest neighbor, k-nearest neighbor, range and ball queries Author: Andrea Tagliasacchi Jon

I am experiencing apparently random crashes from the query files in this package. The files compile just fine, but they don't always work.

I randomly get a "Matlab System Error" containing details indicating a segmentation violation on both R2012a and R2013a (Windows 64 bit). My compiler is Visual Studio 10.0

I am employing the kdtree_ball_query within a loop, where every point in the domain is checked. The points in the domain are shifted then checked again. On R2012a, the crash occurs after the same number of point-shifts (making me think it had something to do with the input data), but in R2013a, it crashes immediately.

I have tried the different query functions all with the same result. The kdtree_build function has never caused a crash. I don't know why this is happening, but it's too bad because otherwise this suite of files would be immensely useful!

Hi, thanks for sharing the code.

I found a strange behavior from the computational execution time:

kdtree_k_nearest_neighbors(tree,P,1);

is far way faster than:

kdtree_nearest_neighbor(tree,P);

being P a point with 25 dimensions.
