录入程序代码，并对该实验代码进行调试，检查程序代码中的语法和语义错误。 编写函数f（x）的代码如下： Romberg算法¨ function z=f(x) if (x~=0) z=sin(x)/x else z=1 end 备注：在实验代码中，首先输入必要的变量的值如下： a=0 b=1 tol=1e-8 待查询检查通过，开始输入执行代码 设置格式format short g查看u的值和sin（u）的值： (Input program code, and debugging code for the experiment to check the program code in the syntax and semantic errors. The preparation of a function f (x) of the code is as follows: Romberg algorithm ¨ function z = f (x) if (x ~ = 0) z = sin (x)/x else z = 1 end Note: In the experimental code, First, enter the necessary value of the variable is as follows: a = 0 b = 1 tol = 1e-8 pending inquiries, checking through, began to enter the implementation of the code format format short g see u, values and sin (u) values:)

this is extended euclid source code

排队论，讨论单窗口单队情形，两窗口单队情形。分别计算平均等待时间，平均逗留时间，平均每分钟服务的顾客人数。(Queuing theory to discuss the situation single-window single team, two windows one team situation. Calculate the average waiting time, average length of stay, the average number of customers per minute service.)

用SLM方法来减小OFDM系统的PAR，给出在不同的M值下，系统的PAR曲线图。(To reduce the use of SLM OFDM system PAR, gives the different values ​ ​ of M, the system PAR of Fig.)

二维插值的应用。二维插值主要应用于图像处理和数据的可视话。主要方法有：最邻近插值；双线形插值；三次样条插值等方法。该源码可以看出其中区别。(Application of two-dimensional interpolation. Two-dimensional interpolation is mainly used in image processing and visualization of data words. Main methods are: the nearest interpolation double linear interpolation cubic spline interpolation and other methods. The source can be seen the difference between them.)

考察一个在热循环中的表面贴片电阻。一般情况下，连接贴片电阻与电极的焊点是其中最薄弱的环节，它通常对温度和时间表现出较强的非线性。为了确保结构的完整性，基于蠕变应变和耗散能进行了疲劳分析。(This case study of a surface patch resistance in a thermal cycle. In general, the solder joint is the weakest link, which usually shows strong nonlinearity in temperature and time. In order to ensure the integrity of the structure, the fatigue analysis is carried out based on the creep strain and dissipation energy.)
