## Member Function Documentation

 MOERTEL::Function * MOERTEL::Function_DualLinear1D::Clone ( ) const` [virtual]`

Clone method.

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

Implements MOERTEL::Function.

 bool MOERTEL::Function_DualLinear1D::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

Implements MOERTEL::Function.
