Function ::kfr_dct_get_temp_size_f64¶
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)Returns the temporary (scratch) buffer size required by the 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 kfr_dct_execute_f64 and kfr_dct_execute_inverse_f64 may improve performance.
Fully qualified name: kfr_dct_get_temp_size_f64(KFR_DCT_PLAN_F64 *)
