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
