ISLocalToGlobalMappingConcatenate

Create a new mapping that concatenates a list of mappings

Synopsis

#include "petscis.h"  
PetscErrorCode ISLocalToGlobalMappingConcatenate(MPI_Comm comm,PetscInt n,const ISLocalToGlobalMapping ltogs[],ISLocalToGlobalMapping *ltogcat)
Not Collective

Input Arguments

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

Output Arguments

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
