Constructor & Destructor Documentation

crp::RealStepFunction::RealStepFunction ( ) [inline]

Default constructor.

crp::RealStepFunction::RealStepFunction	(	const std::vector< double > &	breakpoints,
		const std::vector< double > &	values,
		RealInterval	support = `RealInterval()`
	)

Creates a step from the breakpoints and the corresponding values.

Parameters:

breakpoints	Break points where the steps occur
values	Left associative values for the steps
support	Support of the function

virtual crp::RealStepFunction::~RealStepFunction ( ) [inline, virtual]

Virtual destructor.

const std::vector<double>& crp::RealStepFunction::get_breakpoints ( ) [inline]

Returns the breakpoints.

RealInterval& crp::RealStepFunction::get_support ( ) [inline]

Returns the support of the function.

const std::vector<double>& crp::RealStepFunction::get_values ( ) [inline]

Returns the value at the breakpoints.

virtual double crp::RealStepFunction::operator() ( double x ) [virtual]

Evaluates the function at a given point.

Parameters:

x	Evaluation point

void crp::RealStepFunction::set_data	(	const std::vector< double > &	breakpoints,
		const std::vector< double > &	values,
		RealInterval	support = `RealInterval()`
	)
