Expand description

let new_array = obj.contract_pair(lhs_view, rhs_view);

All pair contractions should implement this trait. It returns a new owned ArrayD. The trait also has a method with a default implementation, obj.contract_and_assign_pair(lhs_view: &ArrayViewD, rhs_view: &ArrayViewD, out: &mut ArrayViewD) -> ().
