Scrpit Body

%question (3) & question (4) x0 =transpose(1:19); tol = 10e-10; nmax = 100; x,niter = NewtonRaphson( x0,tol,nmax );

Main Body

function [ x,niter ] = NewtonRaphson( x0,tol,nmax )

%DATA N = 20; niter = 0; error = 1; x0 = zeros(N,1); dx = zeros(N,1);

while (error > tol && niter < nmax)

    niter = niter + 1;
    x = x0 - ((J_springs(x0))/(F_springs(x0)));
    x0 = x;
    error = max(abs(x-g(x0)));

end

for i = 2:N-2

dx(i) = x(i)-x(i-1);

end
