Detailed Description

Class for constructing the identity map as a DiscreteLinearOperator. This is the discrete embedding matrix when the domain space is a subspace of the range space. Otherwise, a dof projection matrix is constructed.

Member Function Documentation

virtual void mfem::IdentityInterpolator::AssembleElementMatrix2 ( const FiniteElement &  trial_fe, const FiniteElement &  test_fe, ElementTransformation &  Trans, DenseMatrix &  elmat  )

inlinevirtual

Compute the local matrix representation of a bilinear form a(u,v) defined on different trial (given by u) and test (given by v) spaces. The rows in the local matrix correspond to the test dofs and the columns – to the trial dofs.

Reimplemented from mfem::BilinearFormIntegrator.
