[Boost-users] multi_array: creating a view to a single element

Hey All!

 

I'm sure there's got to be a way, and unfortunately, the boost users
archive is "down for maintenance" so I can't search there. Basically, I
have a 2 Dimensional array and I would like to be able to access the
center of that array using a variable that maps to some index (for
example, element[3][3] in a 7x7 array).

 

Can someone tell me how to do this? I tried to create a view to a 0
Dimensional array, but that wouldn't work (not surprisingly).

 

FWIW, here's what I tried:

array_type::array_view<0>::type center(myarray[ boost::indices[3][3] ]);

 

I can do this:

Array_type::array_view<1>::type center(myarray[
boost::indices[range(3,3)][3] ]);

 

But then I access the center by doing

center[0]...

 

I guess that'll work, but I wouldn't consider that ideal. Anyone?
Anyone? Bueller? Bueller?

 

Thanks a bunch!

Daniel
