Function Documentation

reverse()

template<typename T , size_t SIMD_WIDTH>

static Vec< T, SIMD_WIDTH > simd::reverse ( const Vec< T, SIMD_WIDTH > & a )

static

Reverses the order of the elements of a Vec.

Parameters

a	Vec to reverse

Returns

Vec containing the elements of the input Vec in reverse order

transpose() [1/2]

template<typename T , size_t SIMD_WIDTH>

static void simd::transpose ( const Vec< T, SIMD_WIDTH > inRows[Vec< T, SIMD_WIDTH >::elems], Vec< T, SIMD_WIDTH > outRows[Vec< T, SIMD_WIDTH >::elems] )

inlinestatic

Transposes a matrix held in an array of Vec's.

The matrix must be given as an array of Vec's which are the rows of the matrix. The number of rows must be equal to the number of elements in a Vec (SIMD_WIDTH/sizeof(T)), i.e. the matrix must be square. Overlap between input and output rows is not permitted.

Parameters

[in]	inRows	array of Vec's holding the matrix to be transposed
[out]	outRows	array of Vec's where the transposed matrix is stored

transpose() [2/2]

template<typename T , size_t SIMD_WIDTH>

static void simd::transpose ( Vec< T, SIMD_WIDTH > rows[Vec< T, SIMD_WIDTH >::elems] )

inlinestatic

Transposes a matrix held in an array of Vec's.

The matrix must be given as an array of Vec's which are the rows of the matrix. The number of rows must be equal to the number of elements in a Vec (SIMD_WIDTH/sizeof(T)), i.e. the matrix must be square.

Parameters

[in,out]

rows

array of Vec's holding the matrix to be transposed
