無監督分類方法，可以對一堆數值自動的歸類(Unsupervised classification methods, can be a pile of automatic classification of numerical)

Matlab Signature Recognotion code

说明：  A comparison between two direct torque control strategies for flux and torque ripple reduction for induction motors drives

使用matlab对离散时间信号进行时域和频域分析(Using matlab to the discrete-time signals in time domain and frequency domain analysis)

matlab编程，是初学者的良师益友，十分难得的例子 (matlab programming beginners mentor, a very rare example)

这是我自己写的亲测可用的matlab 牛顿迭代法函数程序(This is the Newton iteration program based on MATLAB written by myself)

这是小波包消噪程序，很简洁，在分析信号之前可能用得上(This is the wavelet packet de-noising procedure is very simple, you may need them before analyzing signals)

说明：  function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.
