MATLAB M文件例子 最简单的精通MATLAB工具箱的函数之一提出了一个共同的问题。MATLAB函数gcf返回当前图形的句柄。但是，它有一个副作用。如果图形不存在，gcf就创建一个，并返回它的句柄。如果想寻找一个图形是否存在于头一个位置，要是没有，又不得不创建，怎么办？函数mmgcf正好实现由其内容所描述的工作。(MATLAB M file example of the simplest function of proficiency in one of MATLAB toolbox put forward a common problem. MATLAB function to return to the current GCF handle graphics. However, it has a side effect. If the graph does not exist, gcf on to create one and return its handle. If you want to find a graphic exist in the first position, if not, they have created, how should I do? Function mmgcf realize its content is described.)

利用Matlab软件编写的轨道不平顺数据分析程序能够对轨检车测得的不平顺数据进行处理,得到功率谱密度分布函数.轨道不平顺分析程序包括轨道不平顺数据预处理、轨道不平顺谱分布函数计算以及根据实测的车体振动加速度,对轨道不平顺与车体振动加速度进行相干分析、提出对行车运行有不利影响的不平顺波长范围等.研究结果表明:车辆的动力特性与轨道不平顺有密切关系.高低不平顺对车体垂向振动影响显著,轨向不平顺对车体水平振动影响显著,水平不平顺对列车垂向、横向振动均有显著影响.(Matlab software written track irregularity data analysis program able to track inspection car irregularity measured data are processed to obtain the power spectral density function. Track Irregularities track irregularity analysis procedures including data preprocessing, track irregularity spectrum distribution function calculations, and based on the measured vibration acceleration of the vehicle, with the body of track irregularity acceleration coherent analysis, have an adverse impact on traffic running irregularity wavelength range, etc. the results show that: the dynamic characteristics of the vehicle and the track irregularity closely related. rough along the vertical vibration of the vehicle significantly, rail irregularity vibration to levels significantly affect the body, the level of irregularity to train the vertical and horizontal vibration significantly affected.)

说明：  参考维基百科（https://en.wikipedia.org/wiki/Variance-based_sensitivity_analysis）的取样过程以及对应的Estimators。理论性的东西就不进行复述了，这里主要阐述用MATLAB（R2018b）对某个特定函数进行Solo indices敏感性分析的过程。大致可分为四个过程：采样，构建函数，函数输出（将样本带入函数得到输出值），计算Sobol指数（估算一阶影响指数和全局影响指数）(Sobol global sensitivity analysis)
