Who can help me to write the secant method code by Octave?

I provide an example of the Newton Raphson Method code, please write the code as the form.

This is code for the Newton Raphson Method

2.3.1 The Secant Method To avoid the issue with the computation of the derivative in the Newton-Raphson Method, an alternative method called the Secant Method can be used. In this method, we simply approximate f'(xn-1) with f(xn-1) - f(xn-2) 2n-1 Xn-2 which leads to the iteration equation f(In-1)(xn-1 Xn-2) In = {n-1- f(In-1) - f(xn-2) For this algorithm we will need two initial values. Further, we will not need to differentiate so we won't use the variable dfh and we won't need to type syms x in the m-file. MO 1 Q function (r, n] =NewtonRaphsonMethod(f, initialValue, tol, nmax) t(1)=initialValue; $$ Initial Value fh=function_handle(f); $$ syms x; $$ to find the derivative symbolically df=diff(f,x); dfh=function_handle (df); 10 11 printf("%s\t\t\tss ", 'n','t (n)'); *% for loop start n=2 since initialValue have t(1) for n=2 : nmax t(n)=(t (n-1) +fh (t (n-1)))/(dfh (t (n-1))); $$ equation to find tan) printf("%d\t\t$18.08 ", n, t(n)); 1 *$ if derivative fh =0 printf error if (dfh(t (n-1))==0) printf("Error"); break; endif $$ if one of them less than tolerance halt program ET if (fh(t (n-1))==0 || (abs(t (n)-t (n-1)))
