[Boost-users] Reusing indexing base from multi_array_ref

Hi,

Any comments?

#include <iostream>
#include <boost/multi_array.hpp>

int main()
{
    using std::cout;
    using std::endl;
    typedef boost::multi_array<double, 2> array_type;
    typedef boost::multi_array_ref<double,2> array_type_ref;
    typedef array_type::index_range range;
    typedef boost::multi_array_types::extent_range extent_range;
    array_type A(boost::extents[extent_range(1,4)][extent_range(1,10)]);
// 3x9
    A[4][2]=95;
    array_type::array_view<1>::type f = A[boost::indices[range()][2]];
    assert(f[3]==A[4][2]); // Would like to have assert(f[3]==A[4][2]). 
    
    f.reindex(1);
    assert(f[4]==A[4][2]); // Do I *have* to reindex in this way? What
if the indexing base gets more complicated?
}
