MatFactorSolveSchurComplementTranspose
Solve the transpose of the Schur complement system computed during the factorization step
Synopsis
#include "petscmat.h"
PetscErrorCode MatFactorSolveSchurComplementTranspose(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()
