matlab图像增强程序举例图像增强程序举例(Matlab image enhancement, for example)

说明：  光伏电池仿真模型,能模拟任意光照强度和环境温度下的光伏电池特性。(Photovoltaic cell simulation model capable of simulating photovoltaic cell characteristics at any light intensity and ambient temperature)

An alternative to Matlab s HIST, function HISTW prevents extreme values in top and bottom percentiles of an input vector affecting the histogram s scaling, obscuring location and shape of the distribution s main mass. Limits of x and y (maximum only) axes can be set, and a marker line drawn at given x position. In contrast to HIST, bin size can be explicitly specified, and relative, rather than absolute, frequencies are plotted.

说明：  计算动力学系统的分岔图，混沌系统，高维混沌系统的分岔图(Calculated bifurcation diagram of dynamical systems, chaotic systems, high-dimensional chaotic system bifurcation diagram)

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.)
