#include "petscis.h" PetscErrorCode ISLocalToGlobalMappingCreate(MPI_Comm comm,PetscInt bs,PetscInt n,const PetscInt indices[],PetscCopyMode mode,ISLocalToGlobalMapping *mapping)Not Collective, but communicator may have more than one process
| comm | - MPI communicator | |
| bs | - the block size | |
| n | - the number of local elements divided by the block size, or equivalently the number of block indices | |
| indices | - the global index for each local element, these do not need to be in increasing order (sorted), these values should not be scaled (i.e. multiplied) by the blocksize bs | |
| mode | - see PetscCopyMode |
Notes: There is one integer value in indices per block and it represents the actual indices bs*idx + j, where j=0,..,bs-1
