FUNCTIONS

13   gsl_sf_erfc
14         Signature: (double x(); double [o]y(); double [o]e())
15
16       Complementary Error Function erfc(x) := 2/Sqrt[Pi] Integrate[Exp[-t^2],
17       {t,x,Infinity}]
18
19       gsl_sf_erfc does not process bad values.  It will set the bad-value
20       flag of all output ndarrays if the flag is set for any of the input
21       ndarrays.
22
23   gsl_sf_log_erfc
24         Signature: (double x(); double [o]y(); double [o]e())
25
26       Log Complementary Error Function
27
28       gsl_sf_log_erfc does not process bad values.  It will set the bad-value
29       flag of all output ndarrays if the flag is set for any of the input
30       ndarrays.
31
32   gsl_sf_erf
33         Signature: (double x(); double [o]y(); double [o]e())
34
35       Error Function erf(x) := 2/Sqrt[Pi] Integrate[Exp[-t^2], {t,0,x}]
36
37       gsl_sf_erf does not process bad values.  It will set the bad-value flag
38       of all output ndarrays if the flag is set for any of the input
39       ndarrays.
40
41   gsl_sf_erf_Z
42         Signature: (double x(); double [o]y(); double [o]e())
43
44       Z(x) :  Abramowitz+Stegun 26.2.1
45
46       gsl_sf_erf_Z does not process bad values.  It will set the bad-value
47       flag of all output ndarrays if the flag is set for any of the input
48       ndarrays.
49
50   gsl_sf_erf_Q
51         Signature: (double x(); double [o]y(); double [o]e())
52
53       Q(x) :  Abramowitz+Stegun 26.2.1
54
55       gsl_sf_erf_Q does not process bad values.  It will set the bad-value
56       flag of all output ndarrays if the flag is set for any of the input
57       ndarrays.
