I'm working on the newton's method on matlab, could someone help me and show what two lines are needed to be added in the codes in order to make this function work? function sample_newton(f, xc, tol, max_iter) % sample_newton(f, xc, tol, max_iter) % finds a root of the given function f over the interval [a, b] using Newton-Raphson method % IN: % f - the target function to find a root of % function handle with two outputs, f(x), f'(x)...
Problem 4 (programming): Create a MATLAB function named mynewton.m to estimate the root for any arbitrary function f given an initial guess xo, an absolute error tolerance e and a maximum number of iterations max iter. Follow mynewton.m template posted in homework 2 folder on TritonED for guidance. You are not required to use the template. The function should return the approximated root ^n and the number of steps n taken to reach the solution. Use function mynewton.m to perform...
[USING R] Write a function bisect(f, lower, upper, tol = 1e-6) to find the root of the univariate function f on the interval [lower, upper] with precision tolerance =< tol (defaulted to be 10-6 ) via bisection, which returns a list consisting of root, f.root (f evaluated at root), iter (number of iterations) and estim.prec (estimated precision). Apply it to the function f(x) = x3 - x - 1 on [1, 2] with precision tolerance 10-6 . Compare it with...
This program has to be written in matlab 2. Write a function to find a root of f(c) using the secant method. Call this routine secant, call the file secant.m; its first line should be function [x,nf] = secant (fname, x0, x1, tol) fname is the name of the m-file which evaluates the function f(x), 20 and 21 are initial approximations to .c", and tol is a stopping tolerance. Your code should return an approximation x = 2X+1 to 3*...
MATLAB help! I have some MATLAB Assignment to do, the proffesor requires all the small parts in order to get full credit. Help me out, thank you f LAB SECTION NAME HW6P3 (30 points) following are infinite series representations of the function, un pra i a script file HW6P3 that determines the value of the function from the sum of the series for a given value of x. The program (1 pt) must prompt the user to enter a value...
must be done in matlab Part B (Based off Week 3 Content) Newtons Method approximates a root of a function by iterating through the equation where n is the nth estimate for the root of the function f(z). In order to it- erate through this method, we need to provide an initial guess for the root, For example, if we apply this method to f(z) = sin(z) using note that f(cos(r) = 1, we sin(1) =-0.5574 cos(1) sin(-0.5574 ) cos(-0.5574)...
MATLAB Write a function with the header function [s, count] = myMonteCarlo(f, xLeft, xRight, tol) which uses bracketing logic and random numbers to solve for the root of f. Start from your code for Problem 1, then modify the update equation to randomly choose a number between xLeft and xRight. That is your xNew. Note your code will take a different number of iterations to find the root every time you run it, even for the exact same initial bracket,...

This is Matlab Problem and I'll attach problem1 and its answer for reference. We were unable to transcribe this imageNewton's Method We have already seen the bisection method, which is an iterative root-finding method. The Newton Rhapson method (Newton's method) is another iterative root-finding method. The method is geometrically motivated and uses the derivative to find roots. It has the advantage that it is very fast (generally faster than bisection) and works on problems with double (repeated) roots, where the...
