ISLocalToGlobalMapping

mappings from an arbitrary local ordering from 0 to n-1 to a global PETSc ordering used by a vector or matrix.

Synopsis

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.
