ISLocalToGlobalMappingApplyBlock
Takes a list of integers in a local block numbering and converts them to the global block numbering
Synopsis
#include "petscis.h"
PetscErrorCode ISLocalToGlobalMappingApplyBlock(ISLocalToGlobalMapping mapping,PetscInt N,const PetscInt in[],PetscInt out[])
Not collective
Input Parameters
| mapping | - the local to global mapping context
|
| N | - number of integers
|
| in | - input indices in local block numbering
|
Output Parameter
out -indices in global block numbering
Notes
The in and out array parameters may be identical.
Example
If the index values are {0,1,6,7} set with a call to ISLocalToGlobalMappingCreate(PETSC_COMM_SELF,2,2,{0,3}) then the mapping applied to 0
(the first block) would produce 0 and the mapping applied to 1 (the second block) would produce 3.
