Detailed Description

2-dimensional simple polynomial.

Polynomial is of the form: c0 + c1*x + c2*y + c3*x^2 + c4*x*y + c5*y^2 + c6*x^3 + c7*x^2*y + c8*x*y^2 + c9*y^3 + ... After construction must call Initialize() or SetCoefficients() before using other methods.

Member Function Documentation

ERRVALUE POLYNOMIAL_2D::AddSample	(	const DPOINT2D &	pos,
		double	value
	)			[inline]

Add sample for polynomial computation.

Parameters:

	pos	Sample position
	value	Sample value

ERRVALUE POLYNOMIAL_2D::AddSample	(	double	x,
		double	y,
		double	value
	)

Add sample for polynomial computation.

Parameters:

	x	Sample X position
	y	Sample Y position
	value	Sample value

ERRVALUE POLYNOMIAL_2D::Compute

(

)

Compute polynomial fitted to previously added samples.

double POLYNOMIAL_2D::Evaluate

(

const DPOINT2D &

pos

)

const [inline]

Evaluate polynomial at specified position.

Parameters:

pos

Position

double POLYNOMIAL_2D::Evaluate	(	double	x,
		double	y
	)			const

Evaluate polynomial at specified position.

Parameters:

y

X position Y position

const DOUBLE_ARRAY<double>& POLYNOMIAL_2D::GetCoefficients

(

)

const [inline]

Get polynomial coefficients.

Coefficients are sequenced by increasing sum of X and Y powers. Eg. value = c0 + [c1*x + c2*y] + [c3*x^2 + c4*x*y + c5*y^2] + [c6*x^3 + c7*x^2*y + c8*x*y^2 + c9*y^3] + ...

ERRVALUE POLYNOMIAL_2D::Initialize

(

unsigned

order

)

Initialize.

Parameters:

order

Polynomial order, maximum of 10

ERRVALUE POLYNOMIAL_2D::SetCoefficients	(	unsigned	order,
		const double *	Coeff
	)

Directly set polynomial coefficients.

Parameters:

	order	Polynomial order, maximum of 10
	Coeff	Coefficient array of size (order + 1) * (order + 2) / 2
