Fast convergence rate
WebOct 15, 2024 · The speed of convergence of the iterative process depends on ρ (D): the smaller the value is, the faster the convergence rate. The spectral radius of D is ρ (D) = … In numerical analysis, the order of convergence and the rate of convergence of a convergent sequence are quantities that represent how quickly the sequence approaches its limit. A sequence $${\displaystyle (x_{n})}$$ that converges to $${\displaystyle x^{*}}$$ is said to have order of … See more Convergence definitions Suppose that the sequence $${\displaystyle (x_{k})}$$ converges to the number $${\displaystyle L}$$. The sequence is said to converge with order $${\displaystyle q}$$ See more Many methods exist to increase the rate of convergence of a given sequence, i.e. to transform a given sequence into one converging faster to the same limit. Such techniques are in general known as "series acceleration". The goal of the transformed … See more A similar situation exists for discretization methods designed to approximate a function $${\displaystyle y=f(x)}$$, which might be an integral being approximated by numerical quadrature, or the solution of an ordinary differential equation (see example below). … See more The simple definition is used in • Michelle Schatzman (2002), Numerical analysis: a mathematical introduction, Clarendon Press, Oxford.
