GaussLegendreRule Constructor

public GaussLegendreRule(
	double intervalBegin,
	double intervalEnd,
	int order
)

Parameters

intervalBegin  Double

Where the interval starts, inclusive and finite.

intervalEnd  Double

Where the interval stops, inclusive and finite.

order  Int32

Defines an Nth order Gauss-Legendre rule. The order also defines the number of abscissas and weights for the rule. Precomputed Gauss-Legendre abscissas/weights for orders 2-20, 32, 64, 96, 100, 128, 256, 512, 1024 are used, otherwise they're calculated on the fly.
