Detailed Description

1-dimensional simple polynomial.

Polynomial is of the form: c[0] + c[1]*x + c[2]*x^2 + ... + c[order]*x^order. After construction must call Initialize() or SetCoefficients() before using other methods.

Member Function Documentation

ERRVALUE POLYNOMIAL_1D::AddSample	(	double	x,
		double	value
	)

Add sample for polynomial computation.

Parameters:

	x	Sample position
	value	Sample value

ERRVALUE POLYNOMIAL_1D::Compute

(

)

Compute polynomial fitted to previously added samples.

double POLYNOMIAL_1D::Evaluate

(

double

x

)

const

Evaluate polynomial at specified position.

Parameters:

x

Position to evaluate at

const DOUBLE_ARRAY<double>& POLYNOMIAL_1D::GetCoefficients

(

)

const [inline]

Get polynomial coefficients.

Coefficient index is same as power for position when evaluating. Eg. value = c[0] + c[1]*x + c[2]*x^2 + ... + c[order]*x^order.

ERRVALUE POLYNOMIAL_1D::Initialize

(

unsigned

order

)

Initialize.

Parameters:

order

Polynomial order, maximum of 15

ERRVALUE POLYNOMIAL_1D::SetCoefficients	(	unsigned	order,
		const double *	Coeff
	)

Directly set polynomial coefficients.

Parameters:

	order	Polynomial order, maximum of 15
	Coeff	Coefficient array of size (order + 1)
