WebThere are two types of iteration: Definite iteration, in which the number of repetitions is specified explicitly in advance. Indefinite iteration, in which the code block executes until some condition is met.

In mathematics, an iterated function is a function X → X (that is, a function from some set X to itself) which is obtained by composing another function f : X → X with itself a certain number of times. The process of repeatedly applying the same function is called iteration. In this process, starting from some initial object, … See more The formal definition of an iterated function on a set X follows. Let X be a set and f: X → X be a function. Defining f as the n-th iterate of f (a notation introduced by Hans Heinrich Bürmann and John Frederick William Herschel See more Upon iteration, one may find that there are sets that shrink and converge towards a single point. In such a case, the point that is converged to is … See more The notion f must be used with care when the equation g (x) = f(x) has multiple solutions, which is normally the case, as in Babbage's equation of the functional roots of the identity map. … See more In general, the following identity holds for all non-negative integers m and n, $${\displaystyle f^{m}\circ f^{n}=f^{n}\circ f^{m}=f^{m+n}~.}$$ This is structurally identical to the property of exponentiation that a a = a , i.e. the special case f(x) = ax. See more If f(x) = x for some x in X (that is, the period of the orbit of x is 1), then x is called a fixed point of the iterated sequence. The set of fixed points is often denoted as Fix(f). … See more If one considers the evolution of a density distribution, rather than that of individual point dynamics, then the limiting behavior is given by the See more If f and g are two iterated functions, and there exists a homeomorphism h such that g = h ○ f ○ h , then f and g are said to be topologically conjugate. Clearly, topological conjugacy is preserved under iteration, as g = h ○ f ○ h. Thus, if one can solve for … See more WebMar 19, 2015 · implementation of iterative function.
