Please solve the following in MATLAB. Please add the comments in each line and provide the coding, window and the command window, try to make the codes as universal as possible. Thank you!! |Create a function file that performs fixed-point iteration to find the squareroot s of a function. Test your code for the following functions. Your inputs should be the g formula, its derivative, an initial guess, and tolerance. Your code must also take convergence into consideration. X^3 - x^2 = x cos(x) = x
