说明：  这是关于EMD法计算样本熵的程序，希望能给各位带来帮助。(This is about the EMD method to calculate the sample entropy program, I hope to help you.)

首先使用罗曼诺夫斯基准则剔除粗大误差，接着判断是否存在系统误差，最终得出数组的均值、方差、标准差等(The first to use Roman Malinowski guidelines eliminate the careless error, and then determine whether there are systematic errors, and ultimately come to the array mean, variance, standard deviation,)

清华大学信号处理原理课程实验，内容是各种卷积计算方法性能的比较(Tsinghua signal processing theory course experiment, the content is the convolution calculation methods compare the performance of)

将波纹钢板桥涵结构简化为单位宽度的固支圆弧梁,同时考虑波纹钢板桥涵结构和土的共同作用,首次建立了该结构的计算模型,推导了该结构位移、应力的解析解.实例计算结果表明:理论计算结果和现场实测结果相当吻合.在此基础上,编制MATLAB程序,进一步分析波纹板厚、波峰高度、波长、结构半径,土体自重、侧压力系数,以及弹性模量对结构位移、应力的影响,为该结构优化设计和施工提供了理论依据.(The simplified structure of corrugated steel culvert unit width clamped circular beam, taking into account the corrugated steel culvert structure and interaction of soil for the first time to establish a computational model of the structure, the structural displacement derived analytical solution of stress. Example calculation the results show that: the theoretical calculations and field measurement results are quite consistent on this basis, the preparation of the MATLAB program, further analysis of corrugated sheet thickness, wave height, wavelength, structure radius, the weight of soil, lateral pressure coefficient, and elastic modulus of the structure. displacement, the impact of stress for the structural optimization design and construction provides a theoretical basis.)

最优控制是现代控制理论的核心，它研究的主要问题是：在满足一定约束条件下，寻求最优控制策略，使得性能指标取极大值或极小值(The optimal control is the core of modern control theory it is the main problem is: conditions meet certain constraints, finding the optimal control strategy, and performance to take the maximum or minimum value)
