Detailed Description

template<typename T, std::size_t n>
class macstl::vec< T, n >

SIMD type.

This platform-independent SIMD type offers valarray-like behavior in a package the size of a single CPU register.

Parameters:

	T	The element value type.
	n	The number of elements.

Note:

The primary template is not actually defined, only the explicit specializations corresponding to actual SIMD types are e.g. in Altivec, vec <short, 8> is defined (corresponding to __vector signed short on that platform) but vec <short, 16> isn't. This allows you to use template metaprogramming to determine whether an actual SIMD type exists on a platform.

Header:

#include <macstl/vec.h>

macstl::altivec, macstl::mmx

Public Types
typedef value_type	init_type
	Type used for static initialization. Usually the same as the value type, but may vary due to C++ template non-type parameter restrictions.
Public Member Functions
	vec (data_type data)
	Constructs from the raw vector data.
	vec ()
	Constructs with all elements zero.
Static Public Member Functions
template<init_type v>
static vec	fill ()
	Fills a vector with the same constant element v.
static vec	fill (value_type v)
	Fills a vector with the same element v.
template<init_type v0...>
static vec	set ()
	Sets a vector with n constant elements, v0...
static vec	set (value_type v0...)
	Sets a vector with n elements, v0...
