std::valarray is the class for representing and manipulating arrays of values. It supports element-wise mathematical operations and various forms of generalized subscript operators, slicing and indirect access. std::valarray and helper classes are defined to be free of certain forms of aliasing, thus allowing operations on these classes to be optimized.
