MatCholeskyFactorNumeric
Performs numeric Cholesky factorization of a symmetric matrix. Call this routine after first calling MatCholeskyFactorSymbolic().
Synopsis
#include "petscmat.h"
PetscErrorCode MatCholeskyFactorNumeric(Mat fact,Mat mat,const MatFactorInfo *info)
Collective on Mat
Input Parameters
| fact | - the factor matrix obtained with MatGetFactor()
|
| mat | - the initial matrix
|
| info | - options for factorization
|
| fact | - the symbolic factor of mat
|
Notes
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().
