◆ eigenvalues()

template<typename T1 , typename T2 , typename T3 >
static void Dune::PDELab::MaxwellEigenvectors< 3 >::eigenvalues ( T1  eps,
T1  mu,
const Dune::FieldVector< T2, 2 *dim > &  e 
)
inlinestatic

Returns eigenvalues in the order

s, s, -s, -s, 0, 0 (s = 1/sqrt(\mu \epsilon)

Parameters
epspermittivity
mupermeability
RTmatrix to be filled

◆ eigenvectors()

template<typename T1 , typename T2 , typename T3 >
static void Dune::PDELab::MaxwellEigenvectors< 3 >::eigenvectors ( T1  eps,
T1  mu,
const Dune::FieldVector< T2, dim > &  n,
Dune::FieldMatrix< T3, 2 *dim, 2 *dim > &  R 
)
inlinestatic

Returns a matrix with columnwise the eigenvectors. They correspond to the eigenvalues in the order

s, s, -s, -s, 0, 0 (s = 1/sqrt(\mu \epsilon)

Parameters
epspermittivity
mupermeability
nunit outer normal vector
Rmatrix to be filled
