FERMI_DIRAC(3pm)
NAME
PDL::GSLSF::FERMI_DIRAC - PDL interface to GSL Special Functions
DESCRIPTION
This is an interface to the Special Function package present in the GNU
Scientific Library. Please note that:
- Complete Fermi-Dirac Integrals:
- F_j(x) := 1/Gamma[j+1] Integral[ t^j /(Exp[t-x] + 1), {t,0,Infinity}]
- Incomplete Fermi-Dirac Integrals:
F_j(x,b) := 1/Gamma[j+1] Integral[ t^j /(Exp[t-x] + 1), {t,b,Infinity}]
SYNOPSIS
FUNCTIONS
- gsl_sf_fermi_dirac_int
- Signature: (double x(); double [o]y(); double [o]e(); int j)
- Complete integral F_j(x) for integer j
- gsl_sf_fermi_dirac_int 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_fermi_dirac_mhalf
- Signature: (double x(); double [o]y(); double [o]e())
- Complete integral F_{-1/2}(x)
- gsl_sf_fermi_dirac_mhalf 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_fermi_dirac_half
- Signature: (double x(); double [o]y(); double [o]e())
- Complete integral F_{1/2}(x)
- gsl_sf_fermi_dirac_half 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_fermi_dirac_3half
- Signature: (double x(); double [o]y(); double [o]e())
- Complete integral F_{3/2}(x)
- gsl_sf_fermi_dirac_3half 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_fermi_dirac_inc_0
- Signature: (double x(); double [o]y(); double [o]e(); double b)
- Incomplete integral F_0(x,b) = ln(1 + e^(b-x)) - (b-x)
- gsl_sf_fermi_dirac_inc_0 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.
