For many cases, users are not able to form full matrices. In this situation, eigenvalues computed from these incomplete matrices do not represent the right physics.

In this case, eigenvalue solver should be able to carry out the right calculations with residual evaluations. This is implemented using shell matrices.

This require a libmesh update libMesh/libmesh#2343
