I need help writing this code in MatLab Grader

HW1_2 problem 3.13/4.1 Start with the Cody template (reproduced below). Tip for using Cody: Be sure to test negative input and zero input in your MATLAB before submitting on Cody function (x, ea) = mySqrt (a, es) #calculates square root by divide and average (chapra 3.13 & chapra 4.1) *[x, ea) = mysqrt(a, es) INPUT a: a scalar real number es: error stopping criterion, % YOUTPUT X: square root of a ea: the final error, % x-a; $replace this line with your code to solve for the square root of x end
