MatLUFactorNumeric#
Performs numeric LU factorization of a matrix. Call this routine after first calling MatLUFactorSymbolic() and MatGetFactor().
Synopsis#
#include "petscmat.h"
PetscErrorCode MatLUFactorNumeric(Mat fact, Mat mat, const MatFactorInfo *info)
Collective
Input Parameters#
fact - the factor matrix obtained with
MatGetFactor()mat - the matrix
info - options for factorization
Notes#
See MatLUFactor() for in-place factorization. See
MatCholeskyFactorNumeric() for the symmetric, positive definite case.
Most users should employ the KSP interface for linear solvers
instead of working directly with matrix algebra routines such as this.
See, e.g., KSPCreate().
Fortran Note#
A valid (non-null) info argument must be provided
