Notas

Clases std::valarray y auxiliar están definidos para estar libre de ciertas formas de aliasing, permitiendo así que las operaciones de estas clases para ser optimizado similar al efecto de la palabra clave restrict en el lenguaje de programación C. Además, las funciones y operadores que toman argumentos valarray pueden devolver objetos proxy para hacer posible que el compilador para optimizar una expresión como v1 = a*v2 + v3; como un solo bucle que se ejecuta v1[i] = a*v2[i] + v3[i]; evitando temporales o pases múltiples. Sin embargo, plantillas de expresión hacer la misma técnica de optimización disponibles para cualquier contenedor C + +, y la mayoría de las bibliotecas numéricas prefieren plantillas de expresión para valarrays de flexibilidad. Algunas implementaciones de C + + biblioteca estándar utilizar plantillas de expresión para ejecutar operaciones eficientes en std::valarray (por ejemplo GNU libstdc + + y libc LLVM + +), y sólo en raras ocasiones se han optimizado valarrays cualquier ejemplo adicional, en 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, plantillas de expresión 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.
