PCFactorSetUpMatSolverType#
Can be called after KSPSetOperators()
or PCSetOperators()
, causes MatGetFactor()
to be called so then one may set the options for that particular factorization object.
Synopsis#

PetscErrorCode PCFactorSetUpMatSolverType(PC pc)
Input Parameter#
pc - the preconditioner context
Note#
After you have called this function (which has to be after the KSPSetOperators()
or PCSetOperators()
) you can call PCFactorGetMatrix()
and then set factor options on that matrix.
This function raises an error if the requested combination of solver package and matrix type is not supported.
