MATLAB question

Write a function to iteratively determine the value of V, taking the following inputs: the variable a, the maximum number of iteration (Nmax ), and the tolerance e. The true error is calculated by e; = \a - (V)ns? 1. Test your function by calculating v10 (a = 10), with a maximum number of iterations equal to 20, and an error smaller than 106. Report the square root and the true error
