Function Documentation

◆ gamma()

long double internal::QGaussLobatto::gamma ( const unsigned int  n)

Evaluate the Gamma function \( \Gamma(n) = (n-1)! \).

Parameters
npoint of evaluation (integer).

Definition at line 96 of file quadrature_lib.cc.

◆ compute_quadrature_weights()

std::vector<long double> internal::QGaussLobatto::compute_quadrature_weights ( const std::vector< long double > &  x,
const int  alpha,
const int  beta 
)

Compute Legendre-Gauss-Lobatto quadrature weights. The quadrature points and weights are related to Jacobi polynomial specified by alpha, beta. x denotes the quadrature points.

Returns
Vector containing weights.
