Function Documentation

template<typename OutputType , typename InputType >

__device__ void convert	(	OutputType	x[],
		InputType	y[],
		const int	N
	)		[inline]

Convert a vector of type InputType to type OutputType.

The main current limitation is that there is an implicit asumption that N * sizeof(OutputType) / sizeof(InputType) is an integer. E.g., you can convert a vector 9 float2s into a vector of 5 float4s.

Parameters:

x	Output vector.
y	Input vector.
N	Length of output vector.
