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

[idc,dist]=knnsearch(qp,p,k) VECTORIZED M-CODE
toc
p=rand(N,dim)
qp=rand(Nq,dim)
Output:
Elapsed time is 0.962640 seconds.
Elapsed time is 18.813100 seconds. )

一个用来计算高维数据线性图形嵌入的matlab函数,是几乎所有线性降维算法(如LPP, NPE, IsoProjection, LSDA.)都要用的一个文件,在这里上传给大家,一定用得着!(A high dimensional data used to calculate the linear graphics embedded matlab function, is that almost all linear dimensionality reduction algorithms (such as LPP, NPE, IsoProjection, LSDA.) Should be used in a document From here to the U.S., we use gained!)
