Subject: [boost] [variadic_templates][mpl]interest in compile time matrix multiplication?

For example, with:
> ***domain_matrix:
> ( 11 12 13 )
> ( 21 22 23 )
the following:
> typedef
> outer_product_pack
> < plus_times_row_column<arg<1>,arg<2> >
> >::apply
> < domain_matrix
> , domain_matrix
> >::type
> outer_plus_times_rows_rows;
>
> std::cout<<"***outer_plus_times_rows_rows:\n";
> for_each<outer_plus_times_rows_rows>(printer);
produces:
> ***outer_plus_times_rows_rows:
> ( 434 794 )
> ( 794 1454 )
The plus and times operations can be replaced with any
compile-time binary operation.
Any interest?
-regards,
Larry
