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.
