Template Parameters

scalar_type

must be float or double

Constructor & Destructor Documentation

plan_cufft_r2c()

template<typename scalar_type>

heffte::plan_cufft_r2c< scalar_type >::plan_cufft_r2c ( cudaStream_t stream, direction dir, int size, int batch, int stride, int rdist, int cdist )

inline

Constructor, takes inputs identical to cufftMakePlanMany().

Parameters

stream	is the CUDA stream to use for the transform
dir	is the direction (forward or backward) for the plan
size	is the number of entries in a 1-D transform
batch	is the number of transforms in the batch
stride	is the distance between entries of the same transform
rdist	is the distance between the first entries of consecutive real sequences
cdist	is the distance between the first entries of consecutive complex sequences
