How do I access the index_range of an array_view? ie.,

typedef boost::multi_array Grid; Grid grid( boost::extents[9][9]); Grid::array_view<2> view = grid[indices[range(), range()]];

for (Grid::index i = view.?????.start(); i != view.?????.finish(); ++i) {....}

where I'm expecting i to take values 0..8 inclusive.

Your code seems to have gotten a bit mangled. Can you post a small compilable example?

I would if I could, but getting it to compile is exactly my problem! I don't understand what I need to write for the "?????" bits. The reference guide for multi_array describes a start() and finish() methods on the index_range type, but I can't see how to get a populated object of type index_range from a multi_array or from a multi_array_view.
