Template:cpp/numeric/valarray/sidebar

Defined in header <valarray>
template< class >
class valarray;

Template:cpp 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. Template:cpp and helper classes are defined to be free of certain forms of aliasing, thus allowing operations on these classes to be optimized.
