Several compound assignment operators are provided.

  void operator*= (const valarray<T>&) const;
  void operator/= (const valarray<T>&) const;
  void operator%= (const valarray<T>&) const;
  void operator+= (const valarray<T>&) const;
  void operator-= (const valarray<T>&) const;
  void operator^= (const valarray<T>&) const;
  void operator&= (const valarray<T>&) const;
  void operator|= (const valarray<T>&) const;
  void operator<<=(const valarray<T>&) const;
  void operator>>=(const valarray<T>&) const;

Remarks

There is no return for the compound operators.
