一个报童从报刊发行中心订报后零售，每卖一份报纸可赚钱a元；若报纸卖不出去，则退回发行处，每退一份要赔钱b元。每天报童卖出的份数是随机的，但报童可以根据以往卖报情况统计得到每天卖k份报纸的概率密度p(k)。 （1） 求报童每天期望收益达到最大（或损失达到最小）的定报量z。 （2） 改变参数a/b的值，观察订报量的最优值变化，画出变化曲线。 试画出仿真流程图，进行程序实现，并对仿真结果进行分析。 (A newsboy subscribe from the press after the retail distribution centers, each sale of a newspaper can make money a million if newspapers can not be sold, then returned to Issue Department, each retire to a loss of a b element. Newsboy sold shares in a day is random, but the newsboy can sell based on past statistics reported to be selling daily newspaper k the probability density p (k). (1) seeking newsboy expected profit per day to maximize (or minimize loss) reported that the volume of fixed-z. (2) change the parameters a/b values, subscribe to observe changes in the volume of the optimal value, draw curve. Simulation test to draw a flow chart for program realization, and simulation results for analysis.)

voronoi图划分，用于点云的三角剖分，生成点云表面模型(voronoi graph partitioning triangulation for point cloud generated point cloud surface model)

加入重复控制，是机器学习的例程，用于信号特征提取、信号消噪。( Join repetitive control, Machine learning routines, For feature extraction, signal de-noising.)

运用Matlab编写最小二乘法拟合程序，并指定标记符颜色或者是标记符（小圆圈、正方形、棱形、正五角星、正六角星和四个方向的三角形）周边线条的颜色。取值在上表。 在所有的能产生线条的命令中，参数LineSepc可以定义线条的下面三个属性：线型、标记符号、颜色进行设置。(The least squares fitting program is programmed by using MATLAB, and the color of the marker or the color of the lines around the marker (small circle, square, prism, pentagon, hexagonal star and triangle in four directions) is specified. Take the values in the table above. In all commands that generate lines, the parameter LineSepc defines the following three attributes of a line: line type, marker symbol, and color.)

用Matlab实现人脸检测的功能，程序正确，可以运行，包含测试图片(Face detection using Matlab functions implement the program correctly, you can run, including the test images)

最小二乘支持向量机算法程序，可用于解决多类分类问题(Least squares support vector machine procedures that can be used to solve multi-class problem)

matlab编写的简单车辆标注程序，要来标注过往的车辆(Matlab prepared by the simple vehicle marked vehicles to mark past)
