Hi Max, I'm afraid that you cannot switch the number of dimensions of a view at runtime, that's a property that is set at compile-time. The best you can do is end up with one dimension of size 1, i.e. instead of: [f ? range_t() : 11] use [f ? range_t() : range_t(11)] Cheers, ron On Dec 18, 2008, at 8:10 AM, loadcom wrote:

Hello,

I'm using boost::multi_array of boost 1_36_0 with VS2003SP1.

I hope I could determine the number of dimensions of a view of a given multi_array at runtime, or something like this:

typedef boost::multi_array array_t; typedef typename array_t::index_range range_t;

array_t array; // ... bool f; array_t::array_view<_>::type view = grid[boost::indices[f? range_t() : 11] [f? range_t(1,2): range_t()][rang_t]];

I'll be appreciated to have any kind of help.

B/Rgds Max
