High order vector finite element method in electromagnetics

The matrices came from analysis of a 9-th order microwave
combline filter with second order (LT\QN) vector finite elements
with different mesh quality. The matrices were used as an
example in our paper [1].

    to lowest level (CT\LN) base functions.

All matrices are sparse and come with right-hand-sides.

The dielFilter* matrices came from analysis of a 4th-pole
dielectric resonator [4] generated with Finite Element Method.
The tetrahedral mesh of the structure was generated with the
Netgen mesher [2].  The matrices were used as an example in
our paper [3].

dielFilterV2clx - complex symmetric matrix (607,232 x 607,232),
    25,309,272 nonzero (real) and 728,900 nonzero (imag) elements.
    First 109,108 unknowns correspond to lowest level base
    functions.

dielFilterV2real - real symmetric matrix (1,157,456 x 1,157,456)
    and 48,538,952 nonzero elements.  First 209,432 unknowns
    correspond to lowest level base functions.

dielFilterV3clx - complex symmetric matrix (420,408 x 420,408),
    32,886,208 nonzero (real) and 3,706,513 (imag) elements. First
    24,716 unknowns correspond to lowest level base functions,
    next 116,152 unknowns correspond to the second level.

dielFilterV3real - real symmetric matrix (1,102,824 x 1,102,824)
    and 89,306,020 nonzero elements. First 66,353 unknowns
    correspond to lowest level base functions, next 305,729
    unknowns correspond to the  second level.

All matrices are sparse and come with right-hand-sides.
