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.
