hyper2f3as
Fas = hyper2f3as(B,D,z)
Asymptotic approximation of $_2F_3({B},{D},-{z})$, z >> 1. This routine calculates the asymptotic expression for the generalized hypergeometric funcion for the case for which there are two numerator parameters and three denominator parameters. The asymptotic expression approximates $_2F_3({B},{D},-{z})$ when Z is large and positive.

Description |
|
B [vector] |
Vector of numerator parameters, must have length 2 |
|
D [vector] |
Vector of denominator parameters, must have length 3 |
|
z [vector] |
Values for which the hypergeometric function is to be evaluated. The values in z that are passed into the routine should be positive; the function values calculated will be asymptotic approximations for $_2F_3({B},{D},-{z})$. |
