ERF(3)

NAME
PDL::GSLSF::ERF - PDL interface to GSL Special Functions

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

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 ndarrays if the flag is set for any of the input ndarrays.

  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 ndarrays if the flag is set for any of the input ndarrays.

  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 ndarrays if the flag is set for any of the input ndarrays.

  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 ndarrays if the flag is set for any of the input ndarrays.

  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 ndarrays if the flag is set for any of the input ndarrays.
