Detailed Description

template<int dim>
class LaplaceIntegrators::Eigen< dim >

Integrator for eigenvalue problems.

Integrates the matrix $A - M$ in the first matrix of the result. where $A$ is the stiffness matrix of the Laplacian, $M$ is the mass matrix and $$ is the shift stored in the variable shift by the constructor.

If two matrices are built, typically on the leaf mesh, the second matrix is the mass matrix.
