Specialization for r2c single precision.

Constructor & Destructor Documentation

plan_stock_fft()

template<typename F , direction dir>

heffte::plan_stock_fft< F, dir >::plan_stock_fft ( int  size, int  howmanyffts, int  stride, int  rdist, int  cdist  )

inline

Constructor taking into account the different sizes for the real and complex parts.

Parameters

size	is the number of entries in a 1-D transform
howmanyffts	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 sequences in the real sequences
cdist	is the distance between the first entries of consecutive sequences in the complex sequences
