Re: [Boost-users] [MultiArray] Banded matrix

Well, I'd like to use a banded_matrix *as* a multi_array. For example:

some_fcn( const multi_array_ref<T,2> & m);

I'd like to pass in an implementation of a multi_array_ref<T,2> that is
optimized to only hold three diagonals of the array (for example).

Should this not be done? :)
