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