DESCRIPTION

This is an interface to the Special Function package present in the Scientific Library.

SYNOPSIS

FUNCTIONS

gsl_sf_erfc

 Signature: (double x(); double [o]y(); double [o]e())

Complementary Error Function erfc(x) := 2/Sqrt[Pi] Integrate[Exp[-t^2], {t,x,Infinity}]

gsl_sf_erfc does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

gsl_sf_log_erfc

 Signature: (double x(); double [o]y(); double [o]e())

Log Complementary Error Function

gsl_sf_log_erfc does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

gsl_sf_erf

 Signature: (double x(); double [o]y(); double [o]e())

Error Function erf(x) := 2/Sqrt[Pi] Integrate[Exp[-t^2], {t,0,x}]

gsl_sf_erf does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

gsl_sf_erf_Z

 Signature: (double x(); double [o]y(); double [o]e())

Z(x) : Abramowitz+Stegun 26.2.1

gsl_sf_erf_Z does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

gsl_sf_erf_Q

 Signature: (double x(); double [o]y(); double [o]e())

Q(x) : Abramowitz+Stegun 26.2.1

gsl_sf_erf_Q does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.
