Specialization of the ComplexOperator built from a pair of Sparse Matrices.
The purpose of this specialization is to construct a single SparseMatrix object which is equivalent to the 2x2 block system that the ComplexOperator mimics. The resulting SparseMatrix can then be passed along to solvers which require access to the CSR matrix data such as SuperLU, STRUMPACK, or similar sparse linear solvers.
See ComplexOperator documentation in operator.hpp for more information.
