PetscErrorCode MatFactorInvertSchurComplement(Mat F)
Logically Collective
Input Parameter#
F - the factored matrix obtained by calling
MatGetFactor()
Notes#
Must be called after MatFactorSetSchurIS().
Call MatFactorGetSchurComplement() or MatFactorCreateSchurComplement() AFTER this call to actually compute the inverse and get access to it.
