Adds a method to the PCMG package for coarse space construction.

Synopsis

#include "petscksp.h" 
PetscErrorCode PCMGRegisterCoarseSpaceConstructor(const char name[], PetscErrorCode (*function)(PC pc, PetscInt l, DM dm, KSP smooth, PetscInt Nc, Mat initGuess, Mat *coarseSp))

Not Collective, No Fortran Support

Input Parameters

• name - name of the constructor

• function - constructor routine

Calling sequence of function

• pc - The PC object

• l - The multigrid level, 0 is the coarse level

• dm - The DM for this level

• smooth - The level smoother

• Nc - The size of the coarse space

• initGuess - Basis for an initial guess for the space

• coarseSp - A basis for the computed coarse space
