29 Jan 2012 k-D tree Perform closest point search or range query using a k-D tree implementation. Author: Guy Shechter Tarek

me too. I had the same problem
"Attempt to execute SCRIPT kdtree as a function:"
...
Error in ==> kdtree_demo at 11
[tmp, tmp, TreeRoot] = kdtree( ReferencePts, []);

Im using windows 7 64 bit with Matlab 2011b

20 Dec 2011 k-D tree Perform closest point search or range query using a k-D tree implementation. Author: Guy Shechter vineet

hi,
thanks for the work.
I am having the same problem of getting an error "Attempt to execute SCRIPT kdtree as a function".
Any idea so that i can implement the code.
---currently using R2010b on windows 7 64 bit.

16 Aug 2011 k-D tree Perform closest point search or range query using a k-D tree implementation. Author: Guy Shechter R, S

Hi,
I use the kdtree tools in matlab on a windows XP system, and ran into a problem when processing too large data sets. If I call kdtreeidx with a too large data set, matlab disappears (closes) after being busy for about half an hour. No error message is provided. A sample code that reproduces the problem on my machine:
%----
xM=randn(1000000,1);
[tmp,tmp,TreeRoot]=kdtreeidx(xM,[]);
%----
My machine has 3.46GB of RAM, which I think should be enough to process a million data points? Are there any configuration settings that can increase the processable size for kdtreeidx?

Thanks for your help!

25 Mar 2011 k-D tree Perform closest point search or range query using a k-D tree implementation. Author: Guy Shechter Nguyen, Duy

when I used the function kdtrridex to find closest index in 6-D a space, the one of the return value is 0 and the message "NULL LL" show up. I tracked the source code and found that variable "LL" in run_queries function got the value "NULL" but I don't understand the reason. Someone explain for me please

Works as advertised. Would help if it could handle NaNs in the input columns.
