Web• The cost of calculating of the method. 8.1 GENERAL PRINCIPLES FOR ITERATIVE METHODS 8.1.1 Convergence Any nonlinear equation f(x)= 0 can be expressed as x = g(x). If x 0 constitutes the arbitrary starting point for the method, it will be seen that the solution x∗ for this equation, x ∗= g(x ), can be reached by the numerical sequence: x ... WebNewton’s method makes use of the following idea to approximate the solutions of f(x) = 0. By sketching a graph of f, we can estimate a root of f(x) = 0. Let’s call this estimate x0. We then draw the tangent line to f at x0. If f ′ (x0) ≠ 0, this tangent line intersects the x -axis at some point (x1, 0).
WebIterative methods are based on splitting the matrix A= (P-A)-A with a so-called `preconditioner' matrix P. The methods differ in how to choose this preconditioner.
