Public Attributes Documentation¶

variable nx¶

size_t fft2d_state_t::nx;

Column count.

variable ny¶

size_t fft2d_state_t::ny;

Row count.

variable plan_f32¶

pocketfft_plan* fft2d_state_t::plan_f32;

CF32 2-D plan.

variable plan_f64¶

pocketfft_plan* fft2d_state_t::plan_f64;

CF64 2-D plan.

variable sign¶

int fft2d_state_t::sign;

-1 forward, +1 inverse.

variable work_trunc¶

double _Complex* fft2d_state_t::work_trunc;

Scratch for a short out. A pocketfft 2-D plan is fixed at ny*nx and writes the whole surface, so it cannot be pointed at a smaller buffer; a truncating call transforms here and copies the prefix. Sized for the widest element (CF64) so one buffer serves both plans, and allocated lazily max_out is ny*nx on every sized call, which is everything the Python binding does.
