Member Function Documentation

cosCoeff()

double npstat::ComparisonDensityFunctor1D::cosCoeff	(	unsigned	k,
		unsigned	nInteg
	)		const

Coefficient of expansion of this function into cosine basis, that is, sqrt(2)*cos(k Pi x). The integration is performed using the rectangle integration rule, with nInteg intervals. nInteg should be substantially larger than k, something like 16*k should work reasonably well.

legendreCoeff()

double npstat::ComparisonDensityFunctor1D::legendreCoeff

(

unsigned

degree

)

const

Coefficient of expansion of this function into shifted Legendre polynomials (that is, Legendre polynomials orthonormal on [0, 1]).

legendreSeriesCoeffs()

void npstat::ComparisonDensityFunctor1D::legendreSeriesCoeffs	(	double *	coeffs,
		unsigned	maxDeg
	)		const

All coefficients of the Legendre polynomial expansion of the density, up to the degree requested. The array "coeffs" should have at least maxDeg+1 elements.

trigCoeff()

double npstat::ComparisonDensityFunctor1D::trigCoeff	(	unsigned	k,
		bool	isCosine,
		unsigned	nInteg
	)		const

Coefficient of expansion of this function into trigonometric functions, that is, sqrt(2)*sin(2 k Pi x) and sqrt(2)*cos(2 k Pi x). The integration is performed using the rectangle integration rule, with nInteg intervals. nInteg should be substantially larger than k, something like 32*k should work reasonably well.
