void GaussLegendreData::gauss_nodes_and_weights	(	int	points,
		const Real *&	vx,
		const Real *&	vw
	)

static

Parameters

points	Gauss-Legendre points half-count. If too low/high, the return value will contain the (used) nearest implemented value.
vx	On return, the Gauss-Legendre nodes (nonnegative half of them).
vw	On return, the corresponding Gauss-Legendre weights.

void GaussLegendreData::precompute_nodes_and_weights ( int points )

static

Uses the GSL routine gsl_integration_glfixed_table_alloc.
