Question 3 3 pts Use the Newton-Raphson method with a stopping criterion of es = 0.0001 to solve the following set of equations using an initial guess of x = y = 1.2. What is the value of x? y = -x2 + x + 0.75 y + 5xy = x2 Here is some code to help: function [root, ea,iter) = NewtRaphSystem(func,xo, es,maxiter) % NewtRaphSystem: Newton-Raphson method for systems % [root, ea,iter] = NewtRaphSystem(func,xo, es,maxiter): Solve a system % of equations using Newton-Raphson for a % multivariable system. % input: % func = function that calculates func(x) and the Jacobian J(x) % list of initial guesses % es = stopping criterion % maxiter = maximum allowable iterations % output: % root = roots of the system % ea = approximate relative error % iter = number of iterations performed XO = x = xo: % iter = number of iterations performed X = XO; iter = 0; while (1) [J,f] = func(x); dx = J\f; X = X-dx ea = 100*max(abs(dx./x)); iter = iter +1; if ea= maxiter break end end root = x
