Detailed Description

Class implements the flat forward interpolation technique.

Flat interpolation returns the value of the right node. For $(x,y)$ lying between $(x_j,y_j)$ and $(x_{j+1},y_{j+1})$ the formula for flat forward interpolation is:

$y = y_{j+1}$

Precondition: x vector must be sorted.

Note: Interpolation is only defined for interval defined by the first and the last argument given. The interpolation objects do not extrapolate values outside the interval.

FlatForward * julian::FlatForward::clone ( ) const

virtual

Virtual copy constructor.

Method is an implementation of virtual copy constructor.

Implements julian::Interpolation.

int unsigned julian::FlatForward::getMinSize ( ) const

virtual

return the minimum number of points required by the interpolation

Implements julian::Interpolation.

std::string julian::FlatForward::info ( ) const

virtual

Name of a class.

Method returns string that containing information about class.

Implements julian::Interpolation.

double julian::FlatForward::operator()	(	const std::vector< double > &	x,
		const std::vector< double > &	y,
		const double &	x_int
	)		const

virtual

Performs interpolation.

This operator returns value of interpolant at the point x_init. This value is obtained by flat forward interpolation on the basis of given arguments (vector x) and corresponding values (vector y). If x_init is outside the interval defined by the first and the last element of vector of the arguments operator returns error.

Implements julian::Interpolation.
