valarray& operator*= (const valarray& v); valarray& operator/= (const valarray& v); valarray& operator%= (const valarray& v); valarray& operator+= (const valarray& v); valarray& operator-= (const valarray& v); valarray& operator^= (const valarray& v); valarray& operator&= (const valarray& v); valarray& operator|= (const valarray& v); valarray& operator<<=(const valarray& v); valarray& operator>>=(const valarray& v);
Mandates: The indicated operator can be applied to two operands of type T.
Preconditions: size() == v.size() is true.
The value of an element in the left-hand side of a valarray compound assignment operator does not depend on the value of another element in that left hand side.
Effects: Each of these operators performs the indicated operation on each of the elements of *this and the corresponding element of v.
Returns: *this.
Remarks: The appearance of an array on the left-hand side of a compound assignment does not invalidate references or pointers.
