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.
