用matlab实现的kdtree，kdtree适合用于数据挖掘中用于寻找最近邻。(Using matlab to achieve kdtree, kdtree suitable for data mining used to find the nearest neighbors.)

通过FIR滤波器的自适应调整，不断修正其系统函数，使其与未知系统的参数充分逼近，从而使误差最小，达到系统辨识的目的。(Through the adaptive FIR filter, and continuously revise its system function, so that the unknown system parameters with sufficient approximation, so that the smallest error to achieve system identification purposes.)

附件1是关于FFT算法的详细编程，及详细原理讲解，个人认为，这篇论文对从事信号处理，频谱分析很有帮助，特使是进一步理解FFT算法，很有必要阅读。 程序+原理+运行！ 附件2是关于直接运行FFT工具箱进行频谱分析，请大家可以参考对照，对理解FFT算法肯定有帮助！ (matalb fft 频谱分析)

伺服电机的m代码，可以帮助你利用matlab来完成电机的设置(M-code servo motor that can help you use matlab to complete motor set)

SWTEST Shapiro-Wilk parametric hypothesis test of composite normality. [H, pValue, SWstatistic] = SWTEST(X, ALPHA, TAIL) performs the Shapiro-Wilk test to determine if the null hypothesis of composite normality is a reasonable assumption regarding the population distribution of a random sample X. The desired significance level, ALPHA, is an optional scalar input (default = 0.05). TAIL indicates the type of test (default = 1).
