virtual void mfem::TransposeIntegrator::AddMultPA	(	const Vector &	x,
		Vector &	y
	)		const

inlinevirtual

Method for partially assembled action.

Perform the action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.

This method can be called only after the method AssemblePA() has been called.

Reimplemented from mfem::BilinearFormIntegrator.

virtual void mfem::TransposeIntegrator::AddMultTransposePA	(	const Vector &	x,

inlinevirtual

Method for partially assembled transposed action.

Perform the transpose action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.

This method can be called only after the method AssemblePA() has been called.

Method defining element assembly.

The result of the element assembly is added to the emat Vector if add is true. Otherwise, if add is false, we set emat.
