SYNOPSIS

FUNCTIONS

14   gsl_sf_hyperg_0F1
15         Signature: (double x(); double [o]y(); double [o]e(); double c)
16
17       /* Hypergeometric function related to Bessel functions 0F1[c,x] =
18       Gamma[c]    x^(1/2(1-c)) I_{c-1}(2 Sqrt[x]) Gamma[c] (-x)^(1/2(1-c))
19       J_{c-1}(2 Sqrt[-x])
20
21       gsl_sf_hyperg_0F1 does not process bad values.  It will set the bad-
22       value flag of all output piddles if the flag is set for any of the
23       input piddles.
24
25   gsl_sf_hyperg_1F1
26         Signature: (double x(); double [o]y(); double [o]e(); double a; double b)
27
28       Confluent hypergeometric function  for integer parameters. 1F1[a,b,x] =
29       M(a,b,x)
30
31       gsl_sf_hyperg_1F1 does not process bad values.  It will set the bad-
32       value flag of all output piddles if the flag is set for any of the
33       input piddles.
34
35   gsl_sf_hyperg_U
36         Signature: (double x(); double [o]y(); double [o]e(); double a; double b)
37
38       Confluent hypergeometric function  for integer parameters. U(a,b,x)
39
40       gsl_sf_hyperg_U does not process bad values.  It will set the bad-value
41       flag of all output piddles if the flag is set for any of the input
42       piddles.
43
44   gsl_sf_hyperg_2F1
45         Signature: (double x(); double [o]y(); double [o]e(); double a; double b; double c)
46
47       Confluent hypergeometric function  for integer parameters. 2F1[a,b,c,x]
48
49       gsl_sf_hyperg_2F1 does not process bad values.  It will set the bad-
50       value flag of all output piddles if the flag is set for any of the
51       input piddles.
52
53   gsl_sf_hyperg_2F1_conj
54         Signature: (double x(); double [o]y(); double [o]e(); double a; double b; double c)
55
56       Gauss hypergeometric function 2F1[aR + I aI, aR - I aI, c, x]
57
58       gsl_sf_hyperg_2F1_conj does not process bad values.  It will set the
59       bad-value flag of all output piddles if the flag is set for any of the
60       input piddles.
61
62   gsl_sf_hyperg_2F1_renorm
63         Signature: (double x(); double [o]y(); double [o]e(); double a; double b; double c)
64
65       Renormalized Gauss hypergeometric function 2F1[a,b,c,x] / Gamma[c]
66
67       gsl_sf_hyperg_2F1_renorm does not process bad values.  It will set the
68       bad-value flag of all output piddles if the flag is set for any of the
69       input piddles.
70
71   gsl_sf_hyperg_2F1_conj_renorm
72         Signature: (double x(); double [o]y(); double [o]e(); double a; double b; double c)
73
74       Renormalized Gauss hypergeometric function 2F1[aR + I aI, aR - I aI, c,
75       x] / Gamma[c]
76
77       gsl_sf_hyperg_2F1_conj_renorm does not process bad values.  It will set
78       the bad-value flag of all output piddles if the flag is set for any of
79       the input piddles.
80
81   gsl_sf_hyperg_2F0
82         Signature: (double x(); double [o]y(); double [o]e(); double a; double b)
83
84       Mysterious hypergeometric function. The series representation is a
85       divergent hypergeometric series. However, for x < 0 we have 2F0(a,b,x)
86       = (-1/x)^a U(a,1+a-b,-1/x)
87
88       gsl_sf_hyperg_2F0 does not process bad values.  It will set the bad-
89       value flag of all output piddles if the flag is set for any of the
90       input piddles.
