mat | - the matrix Many br | |
row | - row permutation Many br | |
column | - column permutation Many br | |
info | - structure containing Many br |
levels - number of levels of fill.
expected fill - as ratio of original fill.
1 or 0 - indicating force fill on diagonal (improves robustness for matricesmissing diagonal entries) Many br
Notes: See Users-Manual: ch_mat for additional information about choosing the fill factor for better efficiency. Many br
Most users should employ the simplified KSP interface for linear solvers Many brinstead of working directly with matrix algebra routines such as this. Many brSee, e.g., KSPCreate(). Many br
