Function Documentation

◆ convert()

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 assumption that N * sizeof(OutputType) / sizeof(InputType) is an integer. E.g., you cannot convert a vector 9 float2s into a vector of 5 float4s.

Parameters
xOutput vector.
yInput vector.
NLength of output vector.
