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.
