need help matlab code please

Write a MATLAB function (IncNR) combining the capabilities of both the Incremental Search Method and the Newton-Raphson Method to find allthe roots in a given function Inputs: anonymous furttion AF nitial guess x bracket [xl, XU], where ower x and xU upper x desired error vector of roots vector of errors corresponding to the roots vector of the number o erations Suggested Steps 1. Use the Incremental Search Method to identify the number of roots and the brackets 2. use the Newton-Raphson Method in each of the brackets starting at either the lower domain or the upper domain
