PETSc version 3.17.4
mappings from an arbitrary local ordering from 0 to n-1 to a global PETSc ordering used by a vector or matrix.
typedef struct _p_ISLocalToGlobalMapping* ISLocalToGlobalMapping;
Note: mapping from local to global is scalable; but global
to local may not be if the range of global values represented locally
is very large.
Note: the ISLocalToGlobalMapping is actually a private object; it is included
here for the inline function ISLocalToGlobalMappingApply() to allow it to be inlined since
it is used so often.
