kml_fft(f)_mpi_execute_dft_r2c_ext

Execute the created FFT plan.

C interface:

void kml_fft_mpi_execute_dft_r2c_ext(const kml_fft_plan p, double *in, kml_fft_complex *out, int scale);

void kml_fftf_mpi_execute_dft_r2c_ext(const kml_fftf_plan p, float *in, kml_fftf_complex *out, int scale);

Parameter	Data Type	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
in	Double precision: double* Single precision: float*	Inputs the data to be transformed.	Input
out	Double precision: kml_fft_complex* Single precision: kml_fftf_complex*	Outputs the data generated using FFT.	Output
scale	int	Whether to scale the output result. If scale is set to 1, the output result is scaled. If scale is set to 0, the output result is not processed.	Input
