利用传统有限元方法计算二维possion 方程的特征值问题，网格采用的是三角网格，由matlab 的pdetool产生，一次多项式近似(Using traditional two-dimensional finite element method possion equation eigenvalue problem, the grid uses a triangular mesh is generated by the matlab pdetool, a polynomial approximation)

周期谱估计matlab 程序还有一些数据分析，需要的自行下载(Periodic spectrum estimation matlab procedures, there are some data analysis, the need for self Download)

实验名称:投资组合分析 实验性质：综合性和研究探索性 实验目的：熟练运用投资组合工具箱，学会构造有效前沿组合的方法，掌握最优投资组合的计算方法；给出投资组合VaR 的值。 实验任务：选择股票并从万得下载数据，计算证券的预期收益率、标准差和协方差，设定一组约束条件，构造最优投资组合并计算该组合的Var值。 实验设备：计算机 实验软件：Matlab2013 Wind数据库 选择一组股票作为投资标的，构造投资组合，通过估计收益率均值、计算方差、协方差，计算该投资组合权重、在险价值、画出有效前沿。(Experimental Name: Portfolio Analysis Experimental nature: comprehensiveness and research exploration The purpose of the experiment is to skillfully use the portfolio toolbox, learn to construct effective frontier portfolio method, grasp the best investment portfolio calculation method, and give the value of portfolio VaR. Experimental tasks: select stock and download data from Wan De, calculate the expected return, standard deviation and covariance of securities, set up a set of constraints, construct the optimal portfolio and calculate the Var value of the portfolio. Experimental equipment: computer Experimental software: Matlab2013 Wind database A group of stocks is selected as investment target, and a portfolio is constructed. By estimating the mean value, variance and covariance of the yield, we calculate the portfolio weight, value at risk and draw effective frontier.)

小波包分析提取振动信号中的特征频率，有较好的参考价值，借鉴了主成分分析算法（PCA）。( Wavelet packet analysis to extract vibration signal characteristic frequency, There are good reference value, It draws on principal component analysis algorithm (PCA).)
