#include "petscmat.h" PetscErrorCode MatLUFactor(Mat mat,IS row,IS col,const MatFactorInfo *info)Collective on Mat Many br
mat | - the matrix Many br | |
row | - row permutation Many br | |
col | - column permutation Many br | |
info | - options for factorization, includes Many br |
fill - expected fill as ratio of original fill.
dtcol - pivot tolerance (0 no pivot, 1 full column pivoting)
Run with the option -info to determine an optimal value to use
This changes the state of the matrix to a factored matrix; it cannot be used Many brfor example with MatSetValues() unless one first calls MatSetUnfactored(). Many br
