template< unsigned N, class E1, class E2 > Ret<N*2> combine( const Vec1<N,E1>& a, const Vec2<N,E2>& b );

Combines two vectors into one vector twice as wide. The implementation behaves as if the following set of overloads is provided:

Ret	Vec1	Vec2
int8	int8	int8
uint8	uint8	int8
int16	int16	int16
uint16	uint16	uint16
int32	int32	int32
uint32	uint32	uint32
int64	int64	int64
uint64	uint64	uint64
float32	float32	float32
float64	float64	float64

Parameters

a, b

-

vectors to combine

Return value

A twice as wide vector

r0 = a0
...
rM = aM
r{M+1} = b0
...
r{M+M} = bM
