  • 22: 18.40 Methods of Computation
    The question is then: how is this possible given only F N ( z ) , rather than F ( z ) itself? F N ( z ) often converges to smooth results for z off the real axis for z at a distance greater than the pole spacing of the x n , this may then be followed by approximate numerical analytic continuation via fitting to lower order continued fractions (either Padé, see §3.11(iv), or pointwise continued fraction approximants, see Schlessinger (1968, Appendix)), to F N ( z ) and evaluating these on the real axis in regions of higher pole density that those of the approximating function. …

    The numerically smallest terms are the 5th and 6th. … Optimum truncation occurs just prior to the numerically smallest term, that is, at s 4 . … However, direct numerical transformations need to be used with care. …

    25: 3.5 Quadrature
    About 2 9 = 512 function evaluations are needed. (With the 20-point Gauss–Laguerre formula (§3.5(v)) the same precision can be achieved with 15 function evaluations.) … In adaptive algorithms the evaluation of the nodes and weights may cause difficulties, unless exact values are known. … Convergence acceleration schemes, for example Levin’s transformation (§3.9(v)), can be used when evaluating the series. … A second example is provided in Gil et al. (2001), where the method of contour integration is used to evaluate Scorer functions of complex argument (§9.12). …
    26: 19.36 Methods of Computation
    Numerical differences between the variables of a symmetric integral can be reduced in magnitude by successive factors of 4 by repeated applications of the duplication theorem, as shown by (19.26.18). When the differences are moderately small, the iteration is stopped, the elementary symmetric functions of certain differences are calculated, and a polynomial consisting of a fixed number of terms of the sum in (19.19.7) is evaluated. … F ( ϕ , k ) can be evaluated by using (19.25.5). E ( ϕ , k ) can be evaluated by using (19.25.7), and R D by using (19.21.10), but cancellations may become significant. … Numerical quadrature is slower than most methods for the standard integrals but can be useful for elliptic integrals that have complicated representations in terms of standard integrals. …

    In other circumstances the power series are prone to slow convergence and heavy numerical cancellation. … It should be noted, however, that there is a difficulty in evaluating the coefficients A k ( ζ ) , B k ( ζ ) , C k ( ζ ) , and D k ( ζ ) , from the explicit expressions (10.20.10)–(10.20.13) when z is close to 1 owing to severe cancellation. … A comprehensive and powerful approach is to integrate the differential equations (10.2.1) and (10.25.1) by direct numerical methods. … For applications of generalized Gauss–Laguerre quadrature (§3.5(v)) to the evaluation of the modified Bessel functions K ν ( z ) for 0 < ν < 1 and 0 < x < see Gautschi (2002a). … For evaluation of K ν ( z ) from (10.32.14) with ν = n and z complex, see Mechel (1966). …

    By using this approximation to x as a new point, x 3 = x , and evaluating [ f 0 , f 1 , f 2 , f 3 ] x = 1.12388 6190 , we find that x = 2.33810 7409 , with 9 correct digits. … Then by using x 3 in Newton’s interpolation formula, evaluating [ x 0 , x 1 , x 2 , x 3 ] f = 0.26608 28233 and recomputing f ( x ) , another application of Newton’s rule with starting value x 3 gives the approximation x = 2.33810 7373 , with 8 correct digits. … For theory and applications see Stenger (1993, Chapter 3).
