简化的不平衡磁拉力（UMP）作用于结构，得到动力学作用下的响应。(simply unbalanced magnetic pull and rotor center orbit is gotten)

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.)

matlab编程比较有用的电子书之一，可以经常翻阅进行入门(matlab programming more useful one of the e-book, you can always look for entry-)

affine transform image scrambling

It simulates a simple circuit analysis phasors of current and voltages.

本matlab程序可以对列车称重仪的数据进行分析处理，是一个hilbert-huang变换的很好例子！(The matlab program can train weighing instrument of data analysis and processing, is a hilbert-huang transform a good example!)

迭代蚁群算法思想见浙江大学张兵的博士论文，自编IACA代码，解决了一个动态优化问题实例(ICAC was given by Zhangbin in the paper " Iterative ant-colony algorithm and its application to dynamic optimization of chemical process"(SCI).)
