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 on fact

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().

Developer Note#

The Fortran interface is not autogenerated as the interface definition cannot be generated correctly [due to MatFactorInfo]
