Hello, I have this code that is wrong. I want to solve an equation (f) using newton's method. I want to update my old V value to the eqation for f and df, but I just can't get my head wrapped around it. Could anyone help please?
NB: The answer should be 0.86728 assuming the initial value of V is 0.
P=6;T=2;N = 500;tol = 0.0001;V = zeros(1,N);f = zeros(1,N);df = zeros(1,N);del = 0;Vnew = 0;while del < tol for i = 2:N V(i) = Vnew; f(i) = 3*P*V(i).^3 - P*V(i).^2 + 9*V(i) - 8*T*V(i).^2 - 3; df(i) = 9*P*V(i).^2 - 2*P*V(i) - 16*T*V(i) + 9; Vnew = V(i-1) - (f(i)/df(i)); end del = V(i) - V(i-1);end
