Get temporary (scratch) buffer size for real DFT plan (Single precision).

Parameters
plan Pointer to the DFT plan.
Returns
Temporary buffer size in bytes.

Note

Preallocating a byte buffer of the returned size and passing its pointer to the kfr_dft_execute_f** and kfr_dft_execute_inverse_f** functions may improve performance.
