Synopsis

int MatILUDTFactor(Mat mat,double dt,int maxnz,IS row,IS col,Mat *fact)
Collective on Mat

Input Parameters

mat - the matrix
dt - the drop tolerance
maxnz - the maximum number of nonzeros per row allowed
row - row permutation
col - column permutation

Output Parameters

fact -the factored matrix

Notes

Most users should employ the simplified SLES interface for linear solvers instead of working directly with matrix algebra routines such as this. See, e.g., SLESCreate().
