Detailed Description

template<typename index_t>
class Zoltan2::OrderingSolution< index_t >

The class containing ordering solutions.

Template parameters:
\li \c index_t    index type index_t will be lno_t (local) or gno_t (global)

The ordering solution always contains the permutation and the inverse permutation. These should be accessed through the accessor methods defined in this class, such as getPermutation(). Some ordering algorithms may compute and store other information. Currently, only serial ordering of the local data is supported.

In Zoltan2, perm[i]=j means index i in the reordered vector/matrix corresponds to index j in the old ordering. In Matlab notation, A(perm,perm) is the reordered matrix. This is consistent with SuiteSparse (AMD) and several other ordering packages. Unfortunately, this notation may conflict with a few other packages (such as Ifpack2).
