Detailed Description

template<typename number = double, class VectorType = Vector<number>>
class MGCoarseGridSVD< number, VectorType >

Coarse grid solver using singular value decomposition of LAPACK matrices.

Upon initialization, the singular value decomposition of the matrix is computed. then, the operator() uses
