Simple fixed-point iteration
WebbA function to implement the fixed-point iteration algorithm. This includes monotone, contraction mappings including EM and MM algorithms Usage fpiter (par, fixptfn, objfn=NULL, control=list ( ), ...) Arguments Details control is … Fixed-point iterations are a discrete dynamical system on one variable. Bifurcation theory studies dynamical systems and classifies various behaviors such as attracting fixed points, periodic orbits, or strange attractors. An example system is the logistic map . Iterative methods [ edit] Visa mer In numerical analysis, fixed-point iteration is a method of computing fixed points of a function. More specifically, given a function $${\displaystyle f}$$ defined on the real numbers with … Visa mer An attracting fixed point of a function f is a fixed point xfix of f such that for any value of x in the domain that is close enough to xfix, the fixed-point iteration sequence The natural cosine function ("natural" means in radians, not degrees or other units) has exactly … Visa mer The term chaos game refers to a method of generating the fixed point of any iterated function system (IFS). Starting with any point x0, successive iterations are formed as xk+1 = fr(xk), where fr is a member of the given IFS randomly selected for each iteration.
