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 Many br

Input Parameters

fact - the factor matrix obtained with MatGetFactor() Many br
mat - the initial matrix Many br
info - options for factorization Many br
fact - the symbolic factor of mat Many br

Notes

Most users should employ the simplified KSP interface for linear solvers Many brinstead of working directly with matrix algebra routines such as this. Many brSee, e.g., KSPCreate(). Many br
