MatLUFactorNumeric
Performs numeric LU factorization of a matrix. Call this routine after first calling MatLUFactorSymbolic().
Synopsis
#include "petscmat.h"
PetscErrorCode MatLUFactorNumeric(Mat fact,Mat mat,const MatFactorInfo *info)
Collective on Mat
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 simplified KSP interface for linear solvers
instead of working directly with matrix algebra routines such as this.
See, e.g., KSPCreate().

Developer Note: fortran interface is not autogenerated as the f90
interface defintion cannot be generated correctly [due to MatFactorInfo]
