PSI(3pm) User Contributed Perl Documentation PSI(3pm)NAME
PDL::GSLSF::PSI - PDL interface to GSL Special Functions
DESCRIPTION
This is an interface to the Special Function package present in the GNU Scientific Library.
Poly-Gamma Functions
psi(m,x) := (d/dx)^m psi(0,x) = (d/dx)^{m+1} log(gamma(x))
SYNOPSIS FUNCTIONS
gsl_sf_psi
Signature: (double x(); double [o]y(); double [o]e())
Di-Gamma Function psi(x).
gsl_sf_psi 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_psi_1piy
Signature: (double x(); double [o]y(); double [o]e())
Di-Gamma Function Re[psi(1 + I y)]
gsl_sf_psi_1piy 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_psi_n
Signature: (double x(); double [o]y(); double [o]e(); int n)
Poly-Gamma Function psi^(n)(x)
gsl_sf_psi_n 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.
