Numerical Evaluation of the Gauss Hypergeometric Function with the hypergeo Package
This paper introduces the hypergeo package of R routines for numerical calculation of hypergeometric functions. The package is focussed on efficient and accurate evaluation of the Gauss hypergeometric function over the whole of the complex plane within the constraints of fixed-precision arithmetic. The hypergeometric series is convergent only within the unit circle, so analytic continuation mus...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولGauss’ hypergeometric function
We give a basic introduction to the properties of Gauss’ hypergeometric functions, with an emphasis on the determination of the monodromy group of the Gaussian hyperegeometric equation. Initially this document started as an informal introduction to Gauss’ hypergeometric functions for those who want to have a quick idea of some main facts on hypergeometric functions. It is the startig of a book ...
متن کاملAsymptotics of the Gauss Hypergeometric Function with Large Parameters, I
We obtain asymptotic expansions for the Gauss hypergeometric function F(a+ ε1λ ,b+ ε2λ ;c+ ε3λ ;z) as |λ | →∞ when the ε j are finite by an application of the method of steepest descents, thereby extending previous results corresponding to ε j = 0, ±1 . By means of connection formulas satisfied by F it is possible to arrange the above hypergeometric function into three basic groups. In Part I w...
متن کاملNew series expansions of the Gauss hypergeometric function
The Gauss hypergeometric function 2F1(a, b, c; z) can be computed by using the power series in powers of z, z/(z − 1), 1 − z, 1/z, 1/(1 − z), (z − 1)/z. With these expansions 2F1(a, b, c; z) is not completely computable for all complex values of z. As pointed out in Gil, et al. [2007, §2.3], the points z = e±iπ/3 are always excluded from the domains of convergence of these expansions. Bühring [...
