Member Function Documentation

allowedNPonts()

static std::vector<unsigned> npstat::Gauss1DQuadrature::allowedNPonts ( )

inlinestatic

The complete set of allowed rules, in the increasing order

integrate()

template<typename FcnResult , typename FcnArg >

long double npstat::Gauss1DQuadrature::integrate ( const Functor1< FcnResult, FcnArg > &  fcn ) const

inline

Perform the quadrature

isAllowed()

static bool npstat::Gauss1DQuadrature::isAllowed ( const unsigned  npoints )

inlinestatic

Check if the rule with the given number of points is supported

minimalExactRule()

static unsigned npstat::Gauss1DQuadrature::minimalExactRule ( const unsigned  polyDegree )

inlinestatic

Minimum number of points, among the supported rules, which integrates a polynomial with the given degree exactly (with the appropriate weight). Returns 0 if the degree is out of range.
