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:
