Synopsis
#include "petscpc.h" 
PetscErrorCode PCBDDCCreateFETIDPOperators(PC pc, PetscBool fully_redundant, const char *prefix, Mat *fetidp_mat, PC *fetidp_pc)
Collective
Input Parameters
|  | pc | - the BDDC preconditioning context (setup should have been called before) | 
|  | fully_redundant | - true for a fully redundant set of Lagrange multipliers | 
|  | prefix | - optional options database prefix for the objects to be created (can be NULL) | 
Output Parameters
|  | fetidp_mat | - shell FETI-DP matrix object | 
|  | fetidp_pc | - shell Dirichlet preconditioner for FETI-DP matrix | 
Notes
Currently the only operations provided for FETI-DP matrix are MatMult and MatMultTranspose
