Detailed Description

Class for sesquilinear form

A sesquilinear form is a generalization of a bilinear form to complex-valued fields. Sesquilinear forms are linear in the second argument but the first argument involves a complex conjugate in the sense that:

        a(alpha u, beta v) = conj(alpha) beta a(u, v)

The convention argument in the class's constructor is documented in the mfem::ComplexOperator class found in linalg/complex_operator.hpp.

When supplying integrators to the SesquilinearForm either the real or imaginary integrator can be NULL. This indicates that the corresponding portion of the complex-valued material coefficient is equal to zero.

		BilinearForm *	bfr,
		BilinearForm *	bfi,
		ComplexOperator::Convention	convention = `ComplexOperator::HERMITIAN`
	)

Create a SesquilinearForm on the FiniteElementSpace f, using the same integrators as the BilinearForms bfr and bfi .

The pointer fes is not owned by the newly constructed object.

The integrators are copied as pointers and they are not owned by the newly constructed SesquilinearForm.
