std::valarray-класс для представления и манипулирования массивами значений. Он поддерживает поэлементно математические операции и различные формы операторов обобщенного индекса, нарезки и косвенный доступ.

Original:

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.

Notes

std::valarray и вспомогательные классы определяются быть свободным от определенных форм сглаживания, что позволяет операциях на эти классы должны быть оптимизированы похож на эффект ключевое слово restrict на языке программирования Си. Кроме того, функций и операторов, которые принимают valarray аргументы разрешили вернуться прокси-объекты, чтобы сделать это возможным для компилятора, чтобы оптимизировать выражения, такие как v1 = a*v2 + v3; как единый цикл, который выполняется v1[i] = a*v2[i] + v3[i]; избегая любых временных или несколько проходов. Тем не менее, Выражение шаблонов сделать ту же самую технику оптимизации доступны для любого C + + контейнер, и большинство предпочитает цифровой библиотеки шаблонов для выражения valarrays гибкость. Некоторые C + + библиотека стандартных реализациях использовать шаблоны выражений для осуществления эффективных операций по std::valarray (например, GNU libstdc + + и LLVM Libc + +), и лишь изредка valarrays оптимизированы дальше, например, В Intel Parallel Studio.

Original:

std::valarray and helper classes are defined to be free of certain forms of aliasing, thus allowing operations on these classes to be optimized similar to the effect of the keyword restrict in the C programming language. In addition, functions and operators that take valarray arguments are allowed to return proxy objects to make it possible for the compiler to optimize an expression such as v1 = a*v2 + v3; as a single loop that executes v1[i] = a*v2[i] + v3[i]; avoiding any temporaries or multiple passes. However, Выражение шаблонов make the same optimization technique available for any C++ container, and the majority of numeric libraries prefer expression templates to valarrays for flexibility. Some C++ standard library implementations use expression templates to implement efficient operations on std::valarray (e.g. GNU libstdc++ and LLVM libc++), and only rarely valarrays are optimized any further, e.g. in Intel Parallel Studio.
