#include "mat.h" int MatLUFactor(Mat mat,IS row,IS col,PetscReal f)Collective on Mat
mat | - the matrix | |
row | - row permutation | |
col | - column permutation | |
f | - expected fill as ratio of original fill. |
This changes the state of the matrix to a factored matrix; it cannot be used for example with MatSetValues() unless one first calls MatSetUnfactored().
