GaussLegendreRuleIntegrate(FuncDouble, Double, Double, Double, Int32) Method

public static double Integrate(
	Func<double, double> f,
	double invervalBegin,
	double invervalEnd,
	int order
)

Parameters

f  FuncDouble, Double

The analytic smooth function to integrate.

invervalBegin  Double

Where the interval starts, exclusive and finite.

invervalEnd  Double

Where the interval ends, exclusive 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.
