## Description

### `valarray` public construct/copy/destruct

1.     explicit valarray(const context & context = system::default_context());

2.     explicit valarray(size_t size,
                         const context & context = system::default_context());

3.     valarray(const T & value, size_t size,
                const context & context = system::default_context());

4.     valarray(const T * values, size_t size,
                const context & context = system::default_context());

5.     valarray(const valarray< T > & other);

6.     valarray(const std::valarray< T > & valarray,
                const context & context = system::default_context());

7.     valarray< T > & operator=(const valarray< T > & other);

8.     valarray< T > & operator=(const std::valarray< T > & valarray);

9.     ~valarray();

### `valarray` public member functions

1.     valarray< T > & operator*=(const T &);

2.     valarray< T > & operator/=(const T &);

3.     valarray< T > & operator%=(const T & val);

4.     valarray< T > operator+() const;

5.     valarray< T > operator-() const;

6.     valarray< T > operator~() const;

7.     valarray< char > operator!() const;

   In OpenCL there cannot be memory buffer with bool type, for this reason return type is valarray<char> instead of valarray<bool>. 1 means true, 0 means false.

8.     valarray< T > & operator+=(const T &);

9.     valarray< T > & operator-=(const T &);

10.     valarray< T > & operator^=(const T &);

11.     valarray< T > & operator&=(const T &);

12.     valarray< T > & operator|=(const T &);

13.     valarray< T > & operator<<=(const T &);

14.     valarray< T > & operator>>=(const T &);

15.     valarray< T > & operator*=(const valarray< T > &);

16.     valarray< T > & operator/=(const valarray< T > &);

17.     valarray< T > & operator%=(const valarray< T > &);

18.     valarray< T > & operator+=(const valarray< T > &);

19.     valarray< T > & operator-=(const valarray< T > &);

20.     valarray< T > & operator^=(const valarray< T > &);

21.     valarray< T > & operator&=(const valarray< T > &);

22.     valarray< T > & operator|=(const valarray< T > &);

23.     valarray< T > & operator<<=(const valarray< T > &);

24.     valarray< T > & operator>>=(const valarray< T > &);

25.     size_t size() const;

26.     void resize(size_t size, T value = T());

27.     unspecified operator[](size_t index);

28.     unspecified operator[](size_t index) const;

29.     T() min() const;

30.     T() max() const;

31.     T sum() const;

32.     template<typename UnaryFunction>
          valarray< T > apply(UnaryFunction function) const;

33.     const buffer & get_buffer() const;

### `valarray` private member functions

1.     buffer_iterator< T > begin() const;

2.     buffer_iterator< T > end() const;
