hypergeo_A_nonpos_int: Hypergeometric functions for integer arguments

Description

Hypergeometric functions for A and/or B being integers

Usage

hypergeo_A_nonpos_int(A, B, C, z, tol = 0)
hypergeo_AorB_nonpos_int(A, B, C, z, tol = 0)

Arguments

A,B,C

Parameters for the hypergeometric function

Primary complex argument

tol

tolerance

Details

The point of these functions is that if A and C (or B and C) are identical nonpositive integers, a warning needs to be given. Function hypergeo_AorB_nonpos_int() is a convenience wrapper for hypergeo_A_nonpos_int().
