WebJan 12, 2016 · To solve these problems, we proposed an improved discrete image method, where the following are realized: the real number of the electromagnetic field solution based on the Gaver–Stehfest algorithm for approximate inversion, the exponential approximation of the objective kernel function using the Prony method, the transient electromagnetic ... WebGaver-Stehfest algorithm, usually require high precision. For one of the speciflc inversion routines we consider here (the Euler algorithm), the required precision as a function of n was identifled on p. 272 of Abate, Choudhury and Whitt (1999). For the other two speciflc inversion routines we consider here, Abate and
WebNote that the input precision automatically switches to the multi-precision computing mode for Gaver–Wynn's rho algorithm because of its instability in double precision. As far as we are concerned with electrochemical … WebThe Gaver-Stehfest algorithm is widely used for numerical inversion of Laplace transform. In this paper we provide the first rigorous study of the rate of convergence of the Gaver-Stehfest algorithm. We prove that Gaver-Stehfest approximations converge exponentially fast if the target function is analytic in a neighbourhood of a point and they converge at a …
