本代码是王岩数理统计与MATLAB工程数据分析一书的所有源代码。特点着重基础、强化应用、便自学，是工程数据分析一本很好的书，代码说明也较为详细，本人极力推荐！(This code is WangYan mathematical statistics and data analysis of the MATLAB project book all the source code. Based on characteristics, strengthening the application, and self-study, engineering data analysis is a very good book, code and a more detailed instructions, I highly recommend!)

说明：  层次分析法,解决多属性决策问题,MATLAB源代码.R2019版本测试通过,只需要修改里面的评判矩阵数据即可(Analytic Hierarchy Process (AHP) to solve multi-attribute decision-making problems, the source code of MATLAB. R2019 version passed the test.)

视频捕捉采集，可以学习相关的知识，我的话说完了，谢谢(Microphone-Camera-audio-video)

液压泵振动信号的小波包分解以及功率谱分析，仿真信号的Hilbert谱以及边际谱；仿真信号的小波包能量计算(wavelet packet decomposition and power spectrum of vibration signals for piston pump Hilbert spectrum and marginal spectrum of stimulated signals)

Copula函数的预测，预测相关系数和尾部相关系数值(Predictive correlation coefficient and tail correlation coefficient value)

一个报童从报刊发行中心订报后零售，每卖一份报纸可赚钱a元；若报纸卖不出去，则退回发行处，每退一份要赔钱b元。每天报童卖出的份数是随机的，但报童可以根据以往卖报情况统计得到每天卖k份报纸的概率密度p(k)。 （1） 求报童每天期望收益达到最大（或损失达到最小）的定报量z。 （2） 改变参数a/b的值，观察订报量的最优值变化，画出变化曲线。 试画出仿真流程图，进行程序实现，并对仿真结果进行分析。 (A newsboy subscribe from the press after the retail distribution centers, each sale of a newspaper can make money a million if newspapers can not be sold, then returned to Issue Department, each retire to a loss of a b element. Newsboy sold shares in a day is random, but the newsboy can sell based on past statistics reported to be selling daily newspaper k the probability density p (k). (1) seeking newsboy expected profit per day to maximize (or minimize loss) reported that the volume of fixed-z. (2) change the parameters a/b values, subscribe to observe changes in the volume of the optimal value, draw curve. Simulation test to draw a flow chart for program realization, and simulation results for analysis.)

里面包含一些分数阶函数的工具箱，有些可以相应的查找到(Fractional order function tool kit)

It interpol the averager .......very usefull if you know how to use it, it will help you alot
