Arguments

A

Parameter of hypergeometric function

m,n

Integers

z

Primary complex argument

tol,maxiter

Numerical arguments as per genhypergeo()

method

Character, specifying method to be used

Details

The method argument is described at f15.3.10. All functions' names follow the conventions in Hypergeometric2F1.pdf.

• Function w07.23.06.0026.01(A, n, m, z) returns $hypergeo(A,A+n,A+m,z)$ where $m$ and $n$ are nonnegative integers with $m>=n$.
• Function w07.23.06.0029.01(A, n, m, z) returns $hypergeo(A,A+n,A-m,z)$.
• Function w07.23.06.0031.01(A, n, m, z) returns $hypergeo(A,A+n,A-m,z)$ with $m<=n$. <="" li="">

# Here we catch some answers from Maple (jjM) and compare it with R's:

jjR <- w07.23.06.0026.01(A=1.1 , n=1 , m=4 , z=1+1i) 
# [In practice, one would type 'hypergeo(1.1, 2.1, 5.1, 1+1i)']

stopifnot(Mod(jjM - jjR) < 1e-10)
