HypgFr:
--------------------------------------------------------------------------
Computes the value of the ratio of hypergeometric functions
F(alpha,beta+1;gamma+1,x)
-------------------------
F(alpha,beta;gamma,x)
HypgFr(alpha,0,gamma,x) = HypgF1(alpha,gamma+1,x)
Since version 1.
--------------------------------------------------------------------------
Form:
[F, n] = HypgFr( alpha, beta, gamma, x )
[F, n] = HypgFr( alpha, beta, gamma, x, tol )
[F, n] = HypgFr( alpha, beta, gamma, x, tol, nMax )
