How to write this matlab function for Newton-Raphson root finding method?

write a function with the following header: function In iterations, rootl my root newtonra df, ro, tolerance) phson(f, where: -fis a function handle that represents a real-valued function f de ned and di erentiable on R. ftakes a single input argument that is a scalar of class double (other than NaN, Inf, and Inf) and outputs a single output argument that is a scalar of class double (other than NaN, Inf, and -1nf. -df is a function handle that represents the real-valued function fo (i.e. the derivative of the function f. df takes a single input argument that is a scalar of class double (other than NaN, Inf, and -n) and outputs a single output argument that is a scalar of class double (other than NaN, Inf, and Inf). rois a scalar of class double that is neither NaN, Inf, nor-nf. tolerance is a scalar of class double that is greater than zero and that is di erent from NaN Inf. root is a scalar of class double that is the approximation of the root of the function f, estimated using the Newton-Raphson method starting with the initial guess ro, with as few iterations as possible, and such that abs(froot tolerance. You can assume that, for each case with which your function will be tested, the Newton-Raphson method will converge to a value within the expected tolerance. n iterations is the number of iterations of the Newton-Raphson method used to estimate root. In the Newton-Raphson method, an iteration corresponds to the calculation of a new guess for the root. If the initial guess rois such that abs((o)
