Constructor & Destructor Documentation

MOERTEL::Function_DualLinearTri::Function_DualLinearTri ( int  out )

inline

Constructor.

Parameters

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

Member Function Documentation

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

virtual

Clone method.

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

Implements MOERTEL::Function.

bool MOERTEL::Function_DualLinearTri::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 (dimension 2)
val	(out) : Function values at xi, dimension 3, if NULL on input no evaluation
valdim	(in) : Dimension of val should be 3
deriv	(out) : Derivative of functions at xi, dimension 6, if NULL on input no evaluation

Implements MOERTEL::Function.
