My code works BUT I need to add 1 more thing:

- output- a vector containing the sequence of estimates including the initial guess x0,

function [ r, n ] = myNewton( fHan,dfHan,x0,fTol, itermax ) i = 1;

while abs(fHan(x0)) >= fTol r(i) = x0; n(i) = abs(fHan(x0)); i = i+1; x0 = x0-((fHan(x0))/(dfHan(x0))); end

for j = 1:itermax;

dx = fHan(r) / dfHan(r); r = r - dx

if r < fTol return end end

if abs(fHan(x0)) < fTol r(i) = x0; n(i) = abs(fHan(x0)); end

end

how do I go about doing this? thanks!!
