Functions

FUNCTIONS

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