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

说明： 一个数如果恰好等于它的因子之和，这个数就称为“完数”。例如6=1＋2＋3.编程
找出1000以内的所有完数。
(If a number is just equal to the sum of its factors, this number is called " End of a few." For example 6 = 1+2+3. Programmatically find all finished within a number of 1000.)
