Defining the plot Function for the DocPolynom Class The MATLAB plot function creates line graphs. The overloaded plot function selects the domain of the independent variable to be slightly larger than an interval containing all real roots. Then the polyval method is used to evaluate the polynomial at a few hundred points in the domain:

利用Peng_Robinson EOS 计算常见纯组分气体逸度和密度。利用matlab运行求解。(Peng Robinson is used to calculate the density and fugacity of single component gas at given pressure with Peng-Robinson equation.)

德克萨斯大学奥斯汀分校Baldick Ross教授关于不等式约束最优化问题的课件。详细阐述了最优潮流等典型最优化问题。(Baldick Ross Professor of the University of Texas at Austin courseware inequality constrained optimization problem. The typical elaborate OPF most optimization problems.)

实现了chirp信号的分数阶傅立叶变换，表现出了其能量聚集效果，另外对单频、多频、高斯信号进行了分数阶傅立叶变换(The chirp signal Fractional Fourier Transform, showing the effect of its energy gathered addition of single-frequency, multi-frequency Gaussian signal Fractional Fourier Transform)

用Baum-Welch算法来迭代估计一个隐马尔科夫模型（HMM）的初始状态概率分布以及其状态转移概率矩阵。其中文件有mainfile_B_W.m为主函数，Baum_Welch.m为Baum-Welch算法迭代函数，Forward_variable.m与Backward_variable.m与Gamma_variable.m与Ksi_variable.m是需要计算的四种因子，B_pdf.m为混淆散射概率密度函数。(It s Baum-Welch algorithm for iteratively estimating the initial states probability distribution and state transition probability matrix. In the folder, "mainfile_B_W.m" is the main function, and "Baum_Welch.m" is the iteration Baum-Welch function. Also these four file "Forward_variable.m " "Backward_variable.m" "Gamma_variable.m" "Ksi_variable.m" are used for calculating crucial factors. "B_pdf.m" is the emission probability distrubution function.)
