kml_fft(f)_execute_split_dft

Execute the created FFT plan. However, kml_fft(f)_execute_split_dft can accept new input and output data rather than the plan data as parameters.

Interface Definition

C interface:

void kml_fft_execute_split_dft(const kml_fft_plan p, double *ri, double *ii, double *ro, double *io);

void kml_fftf_execute_split_dft(const kml_fftf_plan p, float *ri, float *ii, float *ro, float *io);

Fortran interface:

CALL KML_FFT_EXECUTE_SPLIT_DFT(P, RI, II, RO, IO);

CALL KML_FFTF_EXECUTE_SPLIT_DFT(P, RI, II, RO, IO);

Description

Input/Output

p
  • Double precision: const kml_fft_plan
  • Single precision: const kml_fftf_plan

FFT plan obtained by calling the plan function.

Input

ri
  • Double precision: double*
  • Single precision: float*

Inputs the real part of the data to be transformed.

Input

ii
  • Double precision: double*
  • Single precision: float*

Inputs the imaginary part of the data to be transformed.

Input

ro
  • Double precision: double*
  • Single precision: float*

Outputs the real part of the data to be transformed.

Output

io
  • Double precision: double*
  • Single precision: float*

Outputs the imaginary part of the data to be transformed.
