说明：  matlab画传输线上电压分布曲线图：传输线特性阻抗Z0=50，求线上电压分布，并画出与z 的关系曲线（用matlab 划出曲线图）。(Matlab draws the curve of voltage distribution on transmission line: the characteristic impedance of transmission line Z0 = 50, calculates the voltage distribution on transmission line, and draws the curve of relationship with Z (draws the curve with matlab).)

利用光的衍射原理， 得到了衍射光栅的光强解析表达式，继而利用MATLAB软件强大的绘图功能，对光强分布的一维、二维图像进行模拟和仿真研究。(Using the diffraction principle of light, the analytical expression of the intensity of the diffraction grating is obtained, and then the one-dimensional and two-dimensional images of the light intensity distribution are simulated by using the powerful drawing function of MATLAB software.)

通过学生成绩管理程序，教师可以轻易地了解学生学习情况，传统手工的学生成绩管理，操作效率低，并且易于出错，查询不方便。本程序实现了对一个班的学生考试成绩按科目进行排序，并统计出各科目的最高分、最低分和平均分的数据。-Management program through student achievement, teachers can easily understand the students learning, the traditional manual student performance management, operational efficiency is low, and error-prone, query inconvenient. This program implements a class of students on test scores sorted by subjects, and the statistics of various subjects, the highest score, lowest score, and average data.
