constexpr std::size_t rank_type /*rev-prod-of-extents*/( rank_type i ) const noexcept;

(exposition only*)

Returns the product of the sizes of extents with index greater than i. The behavior is undefined if i < rank() is false.

Parameters

i - an index above which the sizes of corresponding extents will be multiplied together

Return value

If i + 1 < rank() is true, return the product of extent(k) for all k in range [i + 1rank()), otherwise 1.
