i15.3.6 {hypergeo} | R Documentation

## Helper functions

### Description

Helper functions for equations 15.3.6-15.3.9

### Usage

    i15.3.6(A, B, C)
    i15.3.7(A, B, C)
    i15.3.8(A, B, C)
    i15.3.9(A, B, C)
    j15.3.6(A, B, C)
    j15.3.7(A, B, C)
    j15.3.8(A, B, C)
    j15.3.9(A, B, C)

### Arguments

`A,B,C` | Parameters of the hypergeometric function

### Details

These functions are named for their equation numbers in Abramowitz and Stegun.

Functions `i15.3.?()` return the factors at the beginning of equations 15.3.6-9. These functions return zero if the denominator is infinite (because it includes a gamma function of a nonpositive integer).

Functions `j15.3.?()` check for the appropriate arguments of the gamma function being nonpositive integers.
