function kfr_dct_get_temp_size_f64(KFR_DCT_PLAN_F64 *) capi¶
size_t kfr_dct_get_temp_size_f64(KFR_DCT_PLAN_F64* plan) Get temporary (scratch) buffer size for DCT plan.
| plan | Pointer to the DCT plan. |
| Temporary buffer size in bytes. |
Note
Preallocating a byte buffer of the returned size and passing its pointer to the kfr_dct_execute_f** and kfr_dct_execute_inverse_f** functions may improve performance.
