Understood the potential of this library, I decided to give it for a symbolic price in order to have support to enlarge it. A new more efficient version of the KNN and radius search can be found here.

Thanks! When will k-NN search and radius search be put back into the distribution? Thanks!

I hope I can fix this problem in the next release which is scheduled for early 2010. I don't have a MAC nor a Linux system but I thing I know what the problem is. Thank you I am sorry but I am very busy this days.

I don’t have a MAC nor a Linux system but I thing I know what the problem is.

Thank you

I’ve been using this code under windows but I also would like it to work under Linux. At first the TestMexFiles stopped right away and complained about this line in KNNSearch.cpp:
#include “GLtree.cpp”
where I changed the lower case t to a T.
But there seems to be something else wrong with the DeleteGLTree. This is what happens when I run TestMexFiles now:
…

DELETING THE TREE
 
Mex file entry point is missing. Please check the (case-sensitive) 
spelling of mexFunction (for C MEX-files), or the (case-insensitive) 
spelling of MEXFUNCTION (for FORTRAN MEX-files). 
??? Invalid MEX-file

Do you know what the problem is?

This turns out to be a problem with the declaration of mexFunction. For the solution, see http://www.mathworks.co.kr/matlabcentral/newsreader/view_thread/173095 When I run mex DeleteGLTree.cpp on version R2009a with Mac OS 10.6 (Snow Leopard), I get the following message:

Undefined symbols:
“_mexFunction”, referenced from:
-exported_symbols_list command line option
ld: symbol(s) not found

mex: link of ‘ “DeleteGLTree.mexmaci”‘ failed.
