vector() [1/3] template<typename T , typename... U> vector ( T  , U...    ) -> vector< std::enable_if_t<(std::is_same_v< T, U > &&...), T >, 1+sizeof...(U)> related This deduction guide allows cotila::vector to be constructed like this: cotila::vector v{1., 2.}; // deduces the type of v to be cotila::vector<double, 2>
