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

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.

Note

The in and out array parameters may be identical.
