用于comsol和matlab直接的二次开发(For comsol and matlab direct secondary development)

模拟多小球弹性碰撞,很有趣的一个程序，跟物理有关，不妨看看~(Simulation of multi-ball elastic collision，let us learn it together.)

matlab code to simulate Unscented kalman filter

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)

说明：  对离散数字信号实现QPSK调制，输出调制后的信号(Implementation of discrete digital signals QPSK modulation, the modulated signal output)

this is LSb source code

用响应面法计算可靠度.已知极限状态方程，变量相互独立，服从标准正态分布。(Calculation of reliability by response surface methodology. Known limit state equation, variables are independent standard normal distribution.)
