Detailed Description

Blueprint for generating a cubic spline satisfying C2 constraints.

Generates a blueprint for creating cubic splines on a set of data satisfying a heuristic that automatically generates y' values at the via points. These are later used to generate the connecting cubics.

The heuristic finds the average of the linear slopes connected to each via point. This specifies the desired slope for that via point.

Constructor & Destructor Documentation

DerivativeHeuristicCubicSpline() [1/2]

ecl::blueprints::DerivativeHeuristicCubicSpline::DerivativeHeuristicCubicSpline ( )

inline

Default constructor.

Default constructor (only utilised by the blueprint compile time assert).

Definition at line 373 of file cubic_spline.hpp.

DerivativeHeuristicCubicSpline() [2/2]

ecl::blueprints::DerivativeHeuristicCubicSpline::DerivativeHeuristicCubicSpline	(	const ecl::Array< double > &	x_set,
		const ecl::Array< double > &	y_set,
		const double	ydot_0,
		const double	ydot_f
	)

Constructor that properly configures/initialises the blueprint.

This constructor uses the heuristic to specify the slope at via points. These are stored and later used to generate the connecting cubics.

Parameters

x_set	: set of data on the domain axis.
y_set	: set of values on the range axis.
ydot_0	: initial derivative value (boundary constraint).
ydot_f	: final derivative value (boundary constraint).

Exceptions

StandardException : throws if it failed to construct [debug mode only].
