Member Function Documentation

MOERTEL::Function * MOERTEL::Function_Linear1D::Clone ( ) const [virtual]

Clone method.

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

Implements MOERTEL::Function.

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.

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.
