Function ::kfr_dft_real_execute_f64¶

`function` kfr_dft_real_execute_f64(KFR_DFT_REAL_PLAN_F64 , kfr_c64 , const kfr_f64 , uint8_t ) capi ¶

void kfr_dft_real_execute_f64(KFR_DFT_REAL_PLAN_F64* plan, kfr_c64* out, const kfr_f64* in,
                              uint8_t* temp)

Parameters
plan	Pointer to the DFT plan.
out	Pointer to output data. May point to the same memory as `in` for in-place execution.
in	Pointer to input data.
temp	Temporary (scratch) buffer. If `NULL` , a scratch buffer of size `kfr_dft_real_get_temp_size_f64(plan)` will be allocated on the stack or heap.

Note

This function reads \(N\) real values from in and writes \(\frac{N}{2}\) ( Perm format) or \(\frac{N}{2}+1\) ( CCs format) complex values to out , where \(N\) is the size passed to kfr_dft_real_create_plan_f64 .

Fully qualified name: kfr_dft_real_execute_f64(KFR_DFT_REAL_PLAN_F64 *, kfr_c64 *, const kfr_f64 *, uint8_t *)
