FUNCTIONS

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