1. MATLAB programming solution in brief
   
   ex16.m -- main script to find root;
   autoRoot.m—this function uses brackPlot.m and newton.m to automatically find brackets and roots of the equation f(x);
   fun.m –evaluates f(x);
   dbydx.m—evaluates f’(x);
   brackPlot.m—finds brackets for the given equation f(x) with xmin and xmax;
   newton.m—finds roots with brackets evaluated by brackPlot.m ;
   
   function r = newton(fun,dbydx,x0,xtol,ftol,verbose)
   % newton Newton's method to find a root of the scalar equation f(x) = 0
   %
   % Synopsis: r = newton(fun,dbydx,x0)
   % r = newton(fun,x0,xtol)
   % r = newton(fun,x0,xtol,ftol)
   % r = newton(fun,x0,xtol,ftol,verbose)
   %
   % Input: fun = (string) name of mfile that returns f(x).
   % dbydx = name of mfile that returns f'(x)
   % x0 = initial guess
