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 Parameters#
- 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 Parameter#
- ltogcat - new mapping 
Note#
This currently always returns a mapping with block size of 1
Developer Notes#
If all the input mapping have the same block size we could easily handle that as a special case
