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

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)

01 May 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 Antonio

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.

great work & thx another time Andrea

am posting this for newbies next readers

1) install a compiler (u have to respect the order ) see here : http://www.mathworks.com/support/solutions/en/data/1-ECUGQX/

2) u have to be in matlab on the folder where the files are, see here :
