#include "petscis.h" PetscErrorCode ISLocalToGlobalMappingConcatenate(MPI_Comm comm,PetscInt n,const ISLocalToGlobalMapping ltogs[],ISLocalToGlobalMapping *ltogcat)Not Collective
| comm | - communicator for the new mapping, must contain the communicator of every mapping to concatenate | |
| n | - number of mappings to concatenate | |
| ltogs | - local to global mappings |
| ltogcat | - new mapping |
Note: this currently always returns a mapping with block size of 1
Developer Note: If all the input mapping have the same block size we could easily handle that as a special case
