DenseMatrix elmat 
) [virtual]
void BilinearFormIntegrator::AssembleElementMatrix2 ( const FiniteElement trial_fe,
const FiniteElement test_fe,
ElementTransformation Trans,
DenseMatrix elmat 
) [virtual]

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 in TransposeIntegrator, MassIntegrator, VectorFEDivergenceIntegrator, VectorFECurlIntegrator, DerivativeIntegrator, VectorFEMassIntegrator, VectorDivergenceIntegrator, GradientInterpolator, IdentityInterpolator, CurlInterpolator, and DivergenceInterpolator.
