说明：  某厂生产甲乙两种口味的饮料,每百箱甲饮料需用原料6千克,工人10名,可获利10万元 每百箱乙饮料需用原料5千克,工人20名,可获利9万元.今工厂共有原料60千克,工人150名,又由于其他条件所限甲饮料产量不超过8百箱.问如何安排生产计划,即两种饮料各生产多少使获利最大.进一步讨论: 1)若投资0.8万元可增加原料1千克,问应否作这项投资. 2)若每百箱甲饮料获利可增加1万元,问应否改变生产计划. (Factory production of beverages and B in two flavors, each box 100 need a drink six kilograms of raw materials, workers 10 to 100,000 yuan profit B beverage cartons per cent five kilograms of raw materials needed, workers 20, the profitability of 90,000 yuan. this plant a total of 60 kilograms of raw materials, 150 workers, and because other conditions do not yield a beverage cartons more than 8 per cent. ask what arrangements the production of projects, namely the production of two the number of drinks to make the biggest profit. further discussion : 1) if the investment 08,000 yuan to increase one kilograms of raw materials and asked whether we should make this investment. 2) If a beverage cartons per cent profit increase 10,000 yuan and asked whether or not to change the production plan.)

关于simulink的一些仿真实例，对初学者有所帮助！(It is a document of PDF about examples of Simulink simulation , to help beginners!)

说明：  对新冠肺炎病例传播数据进行清洗，并进行可视化，包含流向地图和桑基图。(The novel coronavirus pneumonia transmission data were cleaned and visualized, including flow maps and sonkey maps.)

应用背景在假设检验中，通常要检查2个元素是否在同一分布中采样。在直方图的情况下，有没有直接和具体的方式来做它。本代码由本韦尔奇的测试实现了仓和Fisher组合概率法加入最后的P值。关键技术此代码简单地实现来自统计的声音和强大的结果。韦尔奇的测试是用来检查是否有2个人口可能有相同的意思，同时考虑到方差和数量的样本（可能不同），从每一个集。通过样本数的方差对均值的均值进行加权。这可能是有用的比较组的直方图，也考虑到不确定性。斌斌比较然后用Fisher方法使每个韦尔奇的测试作为一个卡方检验的自由度下完成2K的p值，其中K是箱的数目。的代码的最终输出的概率，给出的零假设，我们在稍微不同的条件下观察相同的图像，得到的样品，我们输入的算法。
