Conical: an extended module for computing a numerically satisfactory pair of solutions of the differential equation for conical functions
T. M. Dunster, A. Gil, J. Segura +1
Conical functions appear in a large number of applications in physics and engineering. In this paper we describe an extension of our module CONICAL for the computation of conical f…
Computation of the incomplete gamma function for negative values of the argument
A. Gil, D. Ruiz-Antolín, J. Segura +1
An algorithm for computing the incomplete gamma function for real values of the parameter and negative real values of the argument is presented. The algorithm co…
GammaCHI: a package for the inversion and computation of the gamma and chi-square cumulative distribution functions (central and noncentral)
A. Gil, J. Segura, N. M. Temme
A Fortran 90 module (GammaCHI) for computing and inverting the gamma and chi-square cumulative distribution functions (central and noncentral) is presented. The main novelty of thi…
Computation of the Marcum Q-function
A. Gil, J. Segura, N. M. Temme
Methods and an algorithm for computing the generalized Marcum function () and the complementary function () are described. These functions appear in problem…
Algorithm xxx: Modified Bessel functions of imaginary order and positive argument
Amparo Gil, Javier Segura, Nico M. Temme
Fortran 77 programs for the computation of modified Bessel functions of purely imaginary order are presented. The codes compute the functions , and their der…
