5. (20pts, 2 each) Fill in the blanks for the following MATLAB code of the fixed-point iteration method. function [_--, err,n] = fixed_pt(---,po, tol,-_) % Input: g is a function, tol is maximum allowable error, po is the initial guess % N is the maximum number of interations we set % Output: c is the fixed point, err is the error, n is the number of iterations used. i = 1; while i --- N p = g(___); err = abs(-- - p0); if err --- tol C = ---; n = i; break; end --- = i + 1; po = ----; end end
