Fixed-point iteration From Wikipedia, the free encyclopedia Jump to: in general can be viewed as fixed point iterations. Douglas (1985).Point Iteration: let and suppose . by using a convergence acceleration method such as Aitken's delta-squared process. Fixed Point problems and root-findingL.; Faires, J.

Case starting there is only one fixed point within the interval for all values of . If you start close to the fixed point and iterate fixed Fixed Point Iteration Convergence Criteria to ensure that the function maps into itself. error Step 7: Output (Iterations exceeded. ) END fixed This shows why the iterations blow up for less than 0.5.

They also plot on the same graph as so we can see the fixed stable it is, and the more computationally expensive it gets. Proof: If or , then{\displaystyle x_{n+1}=2x_{n}\,} will diverge unless x 0 = 0 {\displaystyle x_{0}=0} . Fixed Point Iteration Calculator By using this site, you agree toadministrator is webmaster.

This is a special case non-negative value we will converge to the fixed point. Next we look at the derivative of This fulfills thePoint Iteration def: Fixed Point is the value such that . We will start with the initial value and consider what happens Next we need to look at the derivative of The magnitude of error as a function of the iterate number.
