非线性最小二乘问题

该程序是基于小波变换的熵谱，用来提取时间序列的周期成分。熵谱相对于小波谱来说在提取周期成分上有一定优势(The program is based on spectral entropy of wavelet transform to extract time series of the periodic component. Entropy is relative to the small spectral component in the extraction cycle, there are some advantages)

说明：  主要讲述ofdm的原理，非常详细，可供需要者参考！很好(Mainly about the principle of ofdm, very detailed, for those who need it for reference! Well)

使用Matlab开发的设计凸轮的源程序，使用了向量法的设计方法。设计了一个正弦运动规律的凸轮，程序带有较完整的注释，对于初学凸轮设计的人来说应该是一个比较好的参考。(It s the source code of the design of a cam using matlab, which uses the method of vector.)

并联有源滤波器模型,基于瞬时无功功率理论。(A model of APF based on transient capacitive power theory)

对信号计算11/2维切片谱，可用来分析二次相位耦合检测。(Calculation of signal 11/2 dimension slice spectrum can be used to analyze the quadratic phase coupling detection.)

说明：  雨流计数方法源代码，可以用于各种工程类的分析之用(rainflow counting method)

说明：  改进后的Pitch Synchronous Overlap Add方法，用于在不引起失真的情况下，改变语音的基频和时长(Improved Pitch Synchronous Overlap Add method, used in the case does not cause distortion, change of voice fundamental frequency and length of)

刚写完的VSNLMS程序，运行即可得结果。/可直接该参数 (VSNLMS just finish the procedure, it can run results./The parameters can be directly)

实现支持向量回归，能够实现小样本的回归预测分析(Regression analysis to realise the prediction base on small sample)

说明：  本文件是用matlab来实现的D-S证据理论代码。可以进行DS证据理论的推到验证(This document is achieved by matlab code DS evidence theory. DS evidence theory can be pushed to the validation)
