求洛伦兹信号的功率谱matlab程序，可以用来求其他信号的功率谱。(Power Spectrum Estimate )

说明：  乘积的最后三位的值只与乘数和被乘数的后三位有关，与乘数和被乘数的高位无关，利用此来求尾数(The last three values of the product only with the multiplier and the multiplicand on the back three, with a high multiplier and the multiplicand has nothing to do, take advantage of this to seek mantissa)

一个永磁同步电机的滑模变结构仿真，经过测试可以用哦。(A sliding mode variable structure of permanent magnet synchronous motor simulation, can be used.)

卷积码和viterbi译码源程序，用MATLAB实现，本人亲自试验过绝对没有错误，希望对大家有用(Convolutional codes and viterbi decoding source code, using MATLAB to achieve, I personally tested absolutely no mistakes, want to be useful to everyone)

说明：  这是关于自适应的一个m文件，希望对大家有用(This is an m on the adaptive document, we hope to be useful)

这是个人总结的各种聚类算法的优缺点比较，包括了常用的一些聚类算法，如层次聚类算法、分割聚类算法、基于约束的算法等(The comparison of various clustering algorithms by myself,including 5 common clustering algorithms)

给出两个chirp信号相加后，由瞬时频率定义求出的瞬时频率曲线，说明瞬时频率的不确切性；(The sum of two chirp signals are given, after the definition of instantaneous frequency derived from the instantaneous frequency curve, indicating lack of precision in the instantaneous frequency )

this source code is chp6ex13 matlab
