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

Output:

Pid-Rk4
自己做的pid调节，已知输入求输出过程用的是龙格库塔发的4阶程序，对了解rk4有很大帮助(Do the PID regulation, the known input process is the output of 4 order Runge Kutta procedure development, are of great help to understand RK4)

说明： 傅里叶变换能将满足一定条件的某个函数表示成三角函数（正弦和/或余弦函数）或者它们的积分的线性组合。利用傅里叶变换可对语音信号消噪。(ourier transform to meet certain conditions can be expressed as a function of trigonometric functions (sine and/or cosine functions), or their integral linear combination. Fourier transform to denoising the speech signal.)
