#include "petscmat.h" PetscErrorCode MatQRFactorNumeric(Mat fact,Mat mat,const MatFactorInfo *info)Collective on Mat
|fact||- the factor matrix obtained with MatGetFactor()|
|mat||- the matrix|
|info||- options for factorization|
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]
