ANN是一个构造数据索引结果的程序，可以实现最近邻、KD树等功能。ANN is designed for data sets that are small enough that the search structure can be stored in main memory (in contrast to approaches from databases that assume that the data resides in secondary storage). Points ar

K-D树的应用文档，适合对K-D树深入学习的同学。文献对K-D树现状和应用有一定的描述-K- D tree application document, suitable for students to K- D tree in-depth study. Literature on K- D describes the present situation and application of a certain tree

K-d树实现。采用matalb和C++混合编译的方式实现。-kdtree provides a minimalistic implementation of kd-tree. The implementation can be used either inside MATLAB by means of MEX calls, or as a standalone tool, directly a C/C++ program.
