Detailed Description

template<typename T>
class stdext::valarray< T >

Numeric (n-at-a-time) array.

A valarray is a replacement for a C array that allows n-at-a-time operation with various arithmetic, logical and transcendental functions. This implementation is largely a superset of std::valarray functionality, and highly optimized to use SIMD opcodes on supporting CPUs.

Parameters:

T

The element value type, which shall satisfy the following requirements: not an abstract class, reference type or cv-qualified type if a class, must publicly define: default constructor, copy constructor, destructor and assignment operator Default construct + assign == copy construct Destruct + copy construct == assign For example, built-in arithmetic types like char, short, int, float, double.

Header:

#include <macstl/valarray.h>

Public Member Functions
Assignments
valarray &	operator= (const T &x)
	Assigns x to each element.
template<typename Expr>
valarray &	operator= (const impl::term< T, Expr > &other)
	Assigns the other term.
valarray &	operator= (const valarray &other)
	Assigns the other array.
void	resize (std::size_t n, const T &x=T())
	Changes the size to n, copying x to each element.
Constructors and Destructors
template<typename Term>
	valarray (const impl::term< T, Term > &other)
	Constructs a copy of other term.
	valarray (const valarray &other)
	Constructs a copy of other array.
	valarray (const T *x, std::size_t n)
	Constructs an array with copies of the first n elements from x.
	valarray (const T &x, std::size_t n)
	Constructs an array of n elements, each a copy of x.
	valarray (std::size_t n)
