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程序模拟微分方程。各种流行的系统显示混沌运动特征。(This toolbox contains the functions which can be used to simulate some of the well-known fractional order chaotic systems, such as:
- Chen s system,
- Arneodo s system,
- Genesio-Tesi s system,
- Lorenz s system,
- Newton-Leipnik s system,
- Rossler s system,
- Lotka-Volterra system,
- Duffing s system,
- Van der Pol s oscillator,
- Volta s system,
- Lu s system,
- Liu s system,
- Chua s systems,
- Financial system,
- 3 cells CNN.
The functions numerically compute a solution of the fractional nonlinear differential equations, which describe the chaotic system. Each function returns the state trajectory (attractor) for total simulation time. )
