LDLT	LU decomposition: direct, no matrix requirements, robust but a bit slow, Eigen and Pardiso available.
CGDiagonal	Cholesky decomposition pivoting: direct, simmetric positive or negative semidefinite, rather fast, Eigen and Pardiso available.
BiCGSTABDiagonal	Conjugate gradient solver with diagonal (a.k.a. Jacobi) preconditioning: iterative(!), simmetric, Eigen only.
