Detailed Description
template<typename T>
class TBCI::DILU_BdMatrixPreconditioner< T >
Templated incomplete LU preconditioner for the class TBCI::BdMatrixDiag. Incomplete LU decomposition as preconditioner for Krylov subspace methods
Note: Quite fast and efficient preconditioner. More effective than Diagonal (Jacobi) preconditioning, but less effective than ILU0 decomposition. Computational costs slighly above Jacobi. Unfortunately, for not so well conditioned matrices, DILU becomes numerically unstable quite early. Long before the others, so I'd not advice to use it in case you're not confident about a good condition of your matrix.
