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:
