template< unsigned K, unsigned N, class E > Ret extract( const Vec1<N,E>& a );

Extracts a K-th element from the given source vector. The implementation behaves as if the following set of overloads is provided:

Ret	Vec1
int8_t	int8
uint8_t	uint8
int16_t	int16
uint16_t	uint16
int32_t	int32
uint32_t	uint32
int64_t	int64
uint64_t	uint64
float	float32
double	float64

Parameters

a

-

vector to extract data from

Return value

Extracted element (none)

Equivalent operation

r = a[K]
