BruteSearch
K-nearest neighbors 搜索 聚类时经常使用的一种方法 国外网站转载( The following utilities are provided:
- Nearest neighbor
- K-Nearest neighbors
- Radius Search
They al supports N-dimensions and work on double, it is possible to choose if return the distances.
Here is a time comparison with a vectrized m-code:
N=1000000 number of reference points
Nq=100 number of query points
dim=3 dimension of points
k=3 number of neighbor

p=rand(N,dim)
qp=rand(Nq,dim)
Output:
Elapsed time is 0.962640 seconds.
Elapsed time is 18.813100 seconds. )

说明： Matlab是Matlab产品家族的基础，它提供了基本的数学算法，例如矩阵运算、数值分析算法，Matlab集成了 2D和3D图形功能，以完成相应数值可视化的工作，并且提供了一种交互式的高级编程语言——M语言，利用M语言可以通过编写脚本或者函数文件实现用户自己的算法。
这是关于matlab的教程(Matlab family of products is the basis of Matlab, which provides the basic mathematical algorithms, such as matrix computation, numerical analysis algorithms, Matlab integrates 2D and 3D graphics features, in order to complete the corresponding numerical visualization work, and provides an interactive high-level programming languages- M language, the use of M language can function through the preparation of the script or document to achieve the user)
