FDICPreconditioner Class Reference

Faster version of the DICPreconditioner diagonal-based incomplete Cholesky preconditioner for symmetric matrices (symmetric equivalent of DILU) in which the the reciprocal of the preconditioned diagonal and the upper coefficients divided by the diagonal are calculated and stored. More...
