Member Function Documentation

void mfem::PositiveFiniteElement::Project ( Coefficient coeff,
ElementTransformation Trans,
Vector dofs 
) const
virtual

Given a coefficient and a transformation, compute its projection (approximation) in the local finite dimensional space in terms of the degrees of freedom.

Reimplemented from mfem::FiniteElement.

Definition at line 320 of file fe.cpp.

void mfem::PositiveFiniteElement::Project ( const FiniteElement fe,
ElementTransformation Trans,
DenseMatrix I 
) const
virtual

Compute the embedding/projection matrix from the given FiniteElement onto 'this' FiniteElement. The ElementTransformation is included to support cases when the projection depends on it.

Reimplemented from mfem::FiniteElement.
