Develop a Matlab function that finds the root of a function f(x) starting from a given initial estimate r with an estimated relative error of at least e using Newton's method. Name the function myNewton using as input the anonymous function f, the anonymous function fp that is the analytical derivative of f(x), the initial estimate xi, and the required estimated relative error eps. As output, the function should provide four scalar variables: the numerical solution, its tolerance in function, its estimated relative error, and the number of iterations performed. If the requested estimated relative error cannot be reached within N 100 iterations, the function should output an error message and exit. You can debug your function using the first 3 iterations of problem 1b)
