Constructor & Destructor Documentation

MOERTEL::Function_Linear1D::Function_Linear1D ( int out )

inline

Constructor.

Parameters

out	: Level of output information written to stdout ( 0 - 10 )

MOERTEL::Function * MOERTEL::Function_Linear1D::Clone ( ) const

virtual

Clone method.

Makes a deep copy of this instance and returns a pointer to it.

bool MOERTEL::Function_Linear1D::EvaluateFunction	(	const MOERTEL::Segment &	seg,
		const double *	xi,
		double *	val,
		const int	valdim,
		double *	deriv
	)

virtual

Evaluate the function and derivatives at a given local coordinate.

Parameters

xi	(in) : Local coordinate where to evaluate the function
val	(out) : Function values at xi, dimension 2, if NULL on input no evaluation
valdim	(in) : Dimension of val should be 2
deriv	(out) : Derivative of functions at xi, dimension 4, if NULL on input no evaluation
