PETSc version 3.15.5
PCHYPRESetInterpolations
Set interpolation matrices for AMS/ADS preconditioner 
Synopsis
#include "petscpc.h" 
PetscErrorCode PCHYPRESetInterpolations(PC pc, PetscInt dim, Mat RT_PiFull, Mat RT_Pi[], Mat ND_PiFull, Mat ND_Pi[])
Collective on PC
Input Parameters
|  | pc | - the preconditioning context | 
|  | dim | - the dimension of the problem, only used in AMS | 
|  | RT_PiFull | - Raviart-Thomas interpolation matrix | 
|  | RT_Pi | - x/y/z component of Raviart-Thomas interpolation matrix | 
|  | ND_PiFull | - Nedelec interpolation matrix | 
|  | ND_Pi | - x/y/z component of Nedelec interpolation matrix | 
Notes
For AMS, only Nedelec interpolation matrices are needed, the Raviart-Thomas interpolation matrices can be set to NULL.
For ADS, both type of interpolation matrices are needed.
