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().

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