So we expect that the sequence of Wegstein iterations will converge to the fixed point (0,1), but it will diverge from another fixed point (1.88241, 0.778642). This is an open method and does not guarantee to convergence the fixed point. Function fixed_point (p0, N) approximates the solution of an equation f (x) = 0, rewritten in the form x = g (x), which is a sub-function the user has to enter. The advantage with a fixed, but huge, training set is that learning has a fixed training set, which is an assumption made when the algorithms are derived. We need to know that there is a solution to the equation. Since it is open method its convergence is not guaranteed. It is very easy method to find to the root of nonlinear equation by computing fixed point of function. This method is also known as Iterative Method. I Convergence is linear at best, often slow, often in doubt. The equation f (x) = 0 can be written in the form Create a M- le to calculate Fixed Point iterations.

Let f (x) be a function continuous on the interval [a, b] and the equation f (x) = 0 has at least one root on [a, b]. The Newton method x n+1 = x n f(x n) f0(x O, generate sequence {! x = sqrt (sin (x)); But sadly, there is no suggestion as to why this particular form was chosen. The speed of convergence of the iteration sequence can be increased by using a convergence acceleration method such as Aitken's delta-squared process. The application of Aitken's method to fixed-point iteration is known as Steffensen's method, and it can be shown that Steffensen's method yields a rate of convergence that is at least quadratic. The process used is to iterate the expression. A fixed point iteration as you have done it, implies that you want to solve the problem q(x) == x.
