The issue of serializing a multi-array came up here:

http://lists.boost.org/boost-users/2007/06/28639.php

I was wondering if anyone had followed up on this and would be willing to share his/her code.

Here's the code based on the above suggestions. I would have thought that overloading serialize (see below) would permit oa << array and ia

array, but not (compile error : array has no member serialize). Therefore, if I want to embed multi_array in another data-structure, what is the next step?

Thanks in advance. template void load( Archive & ar, boost::multi_array & t, const unsigned int file_version ) { typedef boost::multi_array multi_array_; typedef typename multi_array_::size_type size_; size_ n0; ar >> BOOST_SERIALIZATION_NVP(n0); size_ n1; ar >> BOOST_SERIALIZATION_NVP(n1); t.resize(boost::extents[n0][n1]); ar >> make_array(t.data(), t.num_elements()); } template void save( Archive & ar, const boost::multi_array & t, const unsigned int file_version ) { typedef boost::multi_array multi_array_; typedef typename multi_array_::size_type size_; size_ n0 = (t.shape()[0]); ar << BOOST_SERIALIZATION_NVP(n0); size_ n1 = (t.shape()[1]); ar << BOOST_SERIALIZATION_NVP(n1); ar << boost::serialization::make_array(t.data(), t.num_elements()); } template void serialize( Archive & ar, const boost::multi_array& t, const unsigned int file_version ) { split_free(ar, t, file_version); }
