代码说明:

  电磁波、声波或地震波等数值模拟中常常会用到有限差分法,但是很多文章都只是泛泛而谈时间2阶,空间4阶等等如何用公式,本文给出了任意阶精度的泰勒展开与迭代公式。(Numerical simulation of electromagnetic, acoustic or seismic waves will often use the finite difference method, but many articles are just generalities time two bands, space, etc. How to order 4 formula, this paper presents the accuracy of any order Taylor expansion and iterative formula.)

    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:)
