Function ::kfr_dft_get_temp_size_f32¶
function kfr_dft_get_temp_size_f32(KFR_DFT_PLAN_F32 *) capi¶
size_t kfr_dft_get_temp_size_f32(KFR_DFT_PLAN_F32* plan)Returns the temporary (scratch) buffer size required by the DFT plan.
| plan | Pointer to the DFT plan. |
| Temporary buffer size in bytes. |
Note
Preallocating a byte buffer of the returned size and passing its pointer to kfr_dft_execute_f32 and kfr_dft_execute_inverse_f32 may improve performance.
Fully qualified name: kfr_dft_get_temp_size_f32(KFR_DFT_PLAN_F32 *)
