kml_fft(f/h)_mpi_execute_dft

Execute the created FFT plan. However, kml_fft(f/h)_mpi_execute_dft can accept new input and output data different from the plan data as parameters.

Interface Definition

C interface:

void kml_fft_mpi_execute_dft(const kml_fft_plan p, kml_fft_complex *in, kml_fft_complex *out);

void kml_fftf_mpi_execute_dft(const kml_fftf_plan p, kml_fftf_complex *in, kml_fftf_complex *out);

void kml_ffth_mpi_execute_dft(const kml_ffth_plan p, kml_ffth_complex *in, kml_ffth_complex *out);

Parameters

Parameter	Data Type	Description	Input/Output
p	Double precision: const kml_fft_plan Single precision: const kml_fftf_plan Half precision: const kml_ffth_plan	FFT plan obtained by calling the plan function.	Input
in	Double precision: kml_fft_complex* Single precision: kml_fftf_complex* Half precision: kml_ffth_complex*	Inputs the data to be transformed.	Input
out	Double precision: kml_fft_complex* Single precision: kml_fftf_complex* Half precision: kml_ffth_complex*	Outputs the data generated using FFT.	Output
