◆ 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.

Vector containing weights.
