MatFactorSolveSchurComplement
Solve the Schur complement system computed during the factorization step 
Synopsis
#include "petscmat.h" 
PetscErrorCode MatFactorSolveSchurComplement(Mat F, Vec rhs, Vec sol)
Logically Collective on Mat
Input Parameters
|  | F | - the factored matrix obtained by calling MatGetFactor() | 
|  | rhs | - location where the right hand side of the Schur complement system is stored | 
|  | sol | - location where the solution of the Schur complement system has to be returned | 
Notes
The sizes of the vectors should match the size of the Schur complement
Must be called after MatFactorSetSchurIS()
